Platform Economies Chapter 125 examines the contemporary economy through the devices, payment rails and software platforms that increasingly coordinate everyday exchange. The smartphone is now simultaneously a telephone, identity token, bank interface, shop counter, map, workplace, classroom, ticket office and remittance terminal. Yet digitalisation is not a clean replacement of older institutions. Cash remains important; assisted banking remains essential; households share devices; mobile networks fail; and small merchants combine QR payments with notebooks and cash boxes. The correct historical frame is therefore a layered economy in which digital systems reduce some transaction costs while creating new dependencies on electricity, connectivity, authentication, software design, data governance and platform rules. The scale of India’s payment transition is unmistakable but should be dated carefully. NPCI’s published monthly series records 22.716 billion UPI transactions worth about ₹28.92 lakh crore in June 2026. The RBI’s Digital Payments Index, with March 2018 = 100, reached 516.76 in September 2025. These are national indicators, not district measures for Mithila, Vajji or Anga. Likewise, TRAI reported 89.56 million internet subscriptions in the Bihar telecom service area at the end of March 2026, but that service area includes Jharkhand. The regional historian must therefore resist converting regulatory geographies into cultural geographies and instead combine national rails, service-area infrastructure and local household/merchant evidence. Across the India–Nepal border, digital integration now has a chronology of its own. Indian UPI users gained QR-based person-to-merchant acceptance at participating Nepalese merchants in 2024. In June 2026, India’s UPI and Nepal’s National Payments Interface were linked for real-time person-to-person remittances through participating institutions. These are distinct systems serving different transaction types. Together they show how the older border economy of family remittances, pilgrimage, shopping and petty trade is acquiring a digital layer without eliminating cash, foreign-exchange rules, bank regulation or informal exchange. 125.1 The digital layer of the contemporary economy Digitalisation matters economically when it changes who can transact, at what cost, over what distance and with what record. A QR payment can remove the need for exact change, allow a migrant to support a household instantly and give a micro-enterprise a traceable payment history. An app can match customers and workers without a physical office. At the same time, the device and platform become new intermediaries. Network outages, account freezes, authentication failures, software design and platform commissions can now determine whether a sale or day’s work succeeds. This chapter therefore studies digital systems as institutions of exchange rather than as gadgets. The relevant unit is the transaction chain linking connectivity, identity, payment, merchant acceptance, settlement, records and redress. 12751275 GAJENDRA THAKUR Figure 496 — A digital payment depends on a chain of connectivity, identity, initiation, merchant acceptance and settlement; failure at any link can exclude the user. 125.2 Mobile infrastructure and the problem of regional measurement Telecom statistics are indispensable but easy to misuse. TRAI’s March 2026 quarterly report recorded 89.56 million internet subscriptions and 51.65 internet subscriptions per 100 population in the Bihar telecom service area. Yet the report explicitly notes that this service area includes Jharkhand. Those numbers cannot be labelled Bihar population penetration, still less Mithila, Vajji or Anga penetration. State-level and district-level field evidence is needed to recover the regional pattern. The service-area figures nevertheless establish the scale of the network through which regional households transact. They also show a persistent rural–urban gap: infrastructure expands quickly, but reliable coverage, handset quality, electricity, data affordability and repair access remain spatially uneven. 125.3 Connectivity is not the same as effective access A household can be counted as connected while still being digitally constrained. One smartphone may be shared among several family members; a woman may have an account but not control the SIM linked to it; an elderly user may require assistance; and a weak signal may make time-sensitive authentication impossible. Digital capability therefore combines device access, private control, literacy, language, confidence, accessibility and grievance knowledge. The distinction is economically important because failed or delegated use can reproduce dependence on agents even after formal account opening. For historical analysis, surveys should record who owns the handset, who knows the PIN, who authorises payments, whether the connection works during floods or power cuts, and whether the user can independently detect and contest an incorrect transaction. HISTORY OF MITHILA, VAJJI & ANGA — VOLUME II Figure 497 — Digital inclusion requires both reliable access and the capability to control, understand and contest transactions. 125.4 The mobile phone as a financial terminal The mobile phone has collapsed functions once distributed across a branch, passbook, card terminal and paper receipt. Banking apps and UPI can display balances, transfer money and create transaction histories; wallets and mobile banking can pay utilities and school fees; messages provide confirmation; and cameras turn printed QR codes into acceptance devices. This compression reduces travel and queueing costs, which is especially valuable in dispersed rural settlements. But it also moves security responsibility toward the user. A lost handset, compromised SIM, remote-access scam or deceptive link can expose multiple services at once. The economic history of mobile finance must therefore include not only adoption but the reallocation of transaction costs and risks from institutions to individuals. 125.5 UPI and the reorganisation of small payments UPI has become the central rail for India’s retail instant-payment economy. NPCI’s monthly data show 22.716 billion transactions in June 2026, demonstrating a scale at which small digital payments are no longer an urban novelty. The significance for north and eastern Bihar is not that every transaction is digital, but that the cost of initiating an account-to-account payment has fallen sufficiently for very small merchants, households and travellers to use the same national rail. The system also creates interoperability: a shop need not maintain a separate acceptance relationship with every customer’s bank. For historians, national UPI volume supplies context, while district merchant surveys, bank data and household diaries are needed to measure regional intensity and exclusions. 125.6 Merchant QR codes and low-cost acceptance Merchant QR codes radically lowered the physical cost of accepting digital payments because a printed image can substitute for a dedicated card terminal in many small transactions. Tea stalls, pharmacies, tuition centres, repair shops and market traders can therefore accept account-based payments with minimal equipment. The visible QR sticker, however, should not be mistaken for proof of active use. Merchants may prefer cash for some purchases, face settlement uncertainty, use several QR codes, or route receipts through a family member’s account. The most useful field evidence records transaction frequency, average ticket size, 12771277 GAJENDRA THAKUR settlement account ownership, failure rates, refund practice and whether digital receipts alter bookkeeping or access to formal credit. 125.7 Cash persistence and the hybrid payment economy The contemporary payment economy remains hybrid. RBI research has long noted the coexistence of rapid digital-payment growth and persistent currency demand. In rural Mithila, Vajji and Anga, cash remains useful where network coverage is weak, where small informal transactions are anonymous, where users fear fraud, or where merchants need notes for wholesale purchases and wage payments. Digital transfers can even generate cash demand when welfare or remittance receipts are withdrawn through an ATM or business correspondent. The relevant transformation is therefore not a linear move from cash to cashless exchange but a changing boundary between cash, account transfer, assisted cash-out and platform settlement. Resilience often comes from retaining more than one usable payment channel. 125.8 Assisted digital finance and the last mile Assisted digital finance links sophisticated national payment infrastructure to users who cannot or do not wish to operate it independently. Business correspondents, customer service points and Bank Sakhis perform cash-in/cash-out, authentication, account support and information functions close to the village. This intermediary role can lower travel costs and build trust, but it also creates potential for overcharging, password sharing or mistaken delegation if oversight is weak. Evidence should distinguish transactions initiated by the customer from transactions executed on the customer’s behalf. In a region with high migration and dispersed settlements, assisted finance remains part of digital infrastructure rather than evidence that digitalisation has failed. 125.9 JEEViKA, Bank Sakhis and women-centred digital finance Bihar’s JEEViKA provides a particularly important institutional bridge between women’s collectives and digital finance. BRLPS describes its alternate-banking programme as using community members as Bank Sakhis or business-correspondent agents to expand savings, credit, insurance and digital services. In September 2025, Bihar Rajya JEEViKA Nidhi Saakh Sahkari Sangh was launched as a digitally operated credit institution for JEEViKA-linked women, with 12,000 community cadres being equipped with tablets. The significance is not merely technical. When trusted local women become financial intermediaries, the social location of banking changes. The model also shows that digital inclusion can be organisational: technology works through collective institutions, training and proximity rather than through individual apps alone. 125.10 Direct transfers, Aadhaar and cash-out points Government-to-person transfers helped normalise account-based finance, but a digital credit to an account is not the same as usable money in the household. Aadhaar-linked payment architecture, bank accounts, mobile alerts and the Aadhaar Enabled Payment System can shorten transfer chains and make disbursement more traceable. Yet recipients may still need a correspondent to check balances or withdraw cash. The economics of direct transfer should therefore be measured across the entire route from government sanction to household control, including authentication failures, inactive accounts, cash-out distance and transaction fees. For migrant households, a government transfer and a private remittance can arrive through the same account while serving very different purposes and governance regimes. HISTORY OF MITHILA, VAJJI & ANGA — VOLUME II 125.11 Agriculture, input purchase and farm-side payments Agriculture is increasingly touched by digital payments at the edges of production even where cultivation itself remains materially traditional. Farmers can pay input dealers, receive crop-sale proceeds, transfer wages, recharge electricity accounts and settle transport charges through mobile channels. Farmer-producer organisations can use digital records for aggregation and payments. But farm-side digitalisation is constrained by seasonality, thin margins and the need for immediate liquidity. A digitally paid farmer may withdraw cash to hire labour or purchase from a supplier who does not accept transfers. The key evidence is therefore the sequence of transactions around production and marketing, not merely whether an account exists. Digital traces can illuminate value chains only when interpreted alongside crop calendars, credit relations and market structure. 125.12 Micro-enterprise, records and working-capital visibility For micro-enterprises, digital receipts can create a transaction trail that paper cash sales do not. This can improve bookkeeping, simplify supplier settlement and, under appropriate safeguards, provide evidence for credit assessment. Yet the trail may be fragmented across personal and business accounts, multiple QR providers and cash sales. A small enterprise can become more visible to banks and tax systems without becoming more profitable. Platform fees, data costs and delayed settlements can offset convenience. The correct economic question is whether digital records reduce the cost of working capital and market access, not whether the enterprise has been ‘formalised’ by technology. Formal status, tax registration, creditworthiness and digital visibility are distinct dimensions. 125.13 Street vending and digitally visible small commerce Street vending demonstrates the low threshold of QR-based commerce. A vendor can display a code without purchasing expensive acceptance hardware, enabling customers to pay even when neither side has change. Digital receipts may also help vendors build a record of turnover. Yet the smallest traders operate in environments of insecure space, variable daily earnings and frequent cash purchases. Digital payments do not resolve eviction risk, storage constraints or dependence on informal wholesalers. Nor is the person whose name appears on the QR necessarily the economic owner of the stall. Field research should therefore match the payment account to control of the enterprise and examine how digital acceptance interacts with credit, municipal regulation and household finance. 125.14 E-commerce beyond metropolitan India E-commerce expands the market radius of producers and consumers, but participation depends on more than internet access. Sellers need cataloguing, packaging, reliable pickup, returns management, digital settlement and the ability to absorb platform commissions. Consumers need delivery addresses, trust, payment options and dispute resolution. In smaller towns, national marketplaces coexist with social-media selling, messaging-app orders and local delivery arrangements. For Mithila painting, books, food products and specialised crafts, the platform can connect a producer to distant demand; it can also subordinate the producer to ranking systems and standardised presentation. The economic history of e-commerce must therefore study control over visibility and customer data as well as gross sales. 125.15 Logistics platforms and the new geography of delivery Logistics platforms turn digital orders into physical movement. Warehouses, sorting hubs, courier franchises, delivery riders and address databases make e-commerce possible in places far from metropolitan 12791279 GAJENDRA THAKUR fulfilment centres. The resulting economy is geographically selective: a town can become a distribution node even without large manufacturing, while villages beyond reliable roads or standard service zones face surcharges and delays. Cash-on-delivery further demonstrates the hybrid nature of platform commerce because a digitally ordered good can still be settled in cash. Chapter 124’s roads and Chapter 125’s platforms therefore form one system: software can optimise a route, but it cannot substitute for a usable bridge, all- weather road or accurate last-mile address. 125.16 Ride-hailing and app-mediated mobility Ride-hailing platforms reorganise urban mobility by matching drivers and passengers, displaying prices and processing some payments through an app. Their strongest presence is likely in larger regional cities and transport gateways rather than uniformly across the countryside. The platform can reduce search time for a passenger and idle time for a driver, while maps and ratings standardise parts of the service. Yet drivers bear vehicle, fuel, maintenance and waiting costs, and platform incentives can change rapidly. The economic unit is thus not the fare alone but net earnings after asset and time costs. Local studies should distinguish full-time app drivers, multi-platform drivers, auto-rickshaw integration and informal phone-based booking that imitates platform matching without the same corporate intermediary. 125.17 Food delivery and the urban service economy Food-delivery platforms combine restaurants, cloud kitchens, delivery workers, digital payments, mapping and customer ratings. They can enlarge a restaurant’s market beyond walking distance and create flexible work for riders, but commissions and promotional requirements redistribute margins. Their geography reveals the hierarchy of the urban system: dense zones with enough orders support short delivery cycles, whereas smaller towns may be served selectively or not at all. For regional economic history, the expansion date of service into Darbhanga, Muzaffarpur, Bhagalpur or other centres is less important than the resulting change in restaurant turnover, labour patterns and consumer habits. Platform listings are ephemeral and should be archived as dated evidence rather than assumed to persist. 125.18 Home services and mediated trust Home-service platforms extend app-based matching to repair, beauty, cleaning and other personal services. They promise identity verification, standard prices and rating-based trust where customers once relied on neighbourhood recommendation. For workers, platforms can broaden customer reach and provide scheduling tools; they can also impose commissions, performance metrics and penalties. The regional effect depends on urban density and skill supply. Many services remain coordinated through telephone calls and messaging groups rather than formal apps. This continuum matters because platformisation is not synonymous with incorporation into a large venture-backed company: local digital directories, WhatsApp groups and social-media pages also mediate work, although with different data, pricing and liability structures. 125.19 Gig work, platform work and legal recognition Indian law now formally distinguishes gig and platform work. The Code on Social Security, 2020 defines a gig worker as a person earning outside a traditional employer–employee relationship and recognises platform work as work arranged through an online platform. This matters because the vocabulary determines who can be counted, regulated and covered by schemes. It also warns against calling every casual worker a platform worker. A construction labourer hired at a roadside labour point is a gig-like worker in HISTORY OF MITHILA, VAJJI & ANGA — VOLUME II ordinary speech but not necessarily engaged through a digital platform. Regional labour statistics should therefore record the matching mechanism, payment method, contractual relationship and dependence on an app instead of inferring platform status from occupation alone. 125.20 Social security after the 2025 labour-code commencement The legal framework moved from enactment to operational significance when the Code on Social Security came into force on 21 November 2025. By January 2026, the Labour Ministry reported 12 major aggregators onboarded to the e-Shram aggregator module, while broader e-Shram registration exceeded 31 crore unorganised workers in 2026. These national totals do not tell us how many platform workers live in Mithila, Vajji or Anga, and early platform-worker registration data were incomplete. The policy shift is nevertheless historically important: platform labour moved from an emerging category to an explicitly recognised social-security subject. Future research must track actual scheme coverage, aggregator contributions, portability and claim outcomes rather than equating registration with protection. 125.21 Algorithms, ratings and income volatility Platforms coordinate work through algorithms that workers cannot always observe. Order allocation, surge pricing, acceptance rates, cancellation rules, ratings and incentive thresholds can alter hourly earnings without a conventional supervisor issuing instructions. This produces a distinctive form of economic dependence: the worker may formally choose when to log in but has limited control over the terms of each match. Gross platform earnings therefore overstate welfare unless fuel, vehicle depreciation, unpaid waiting time, data costs and accident risk are deducted. Longitudinal worker diaries are especially valuable because a one-day survey misses changing incentive structures. The history of platform work will depend on preserving app screenshots, payout statements and worker testimony before interfaces and rules change. Figure 499 — Platform economies coordinate customers, merchants and workers through software while redistributing costs, information and risk. 125.22 Gendered access, device ownership and platform participation Digital inclusion is gendered because device control, mobility, literacy and household norms shape who can transact privately. Women’s collective institutions such as JEEViKA can reduce these barriers by creating trusted local intermediaries and training networks. At the same time, platform work in mobility and delivery can remain male dominated because of vehicle ownership, safety concerns and late-hour work. Digital 12811281 GAJENDRA THAKUR finance may expand women’s control over savings only when the woman controls the account, SIM, authentication method and information. Counting women-owned accounts without recording effective control can therefore exaggerate autonomy. Regional surveys should combine sex-disaggregated ownership data with questions on who initiates transactions and who decides how digital income is used. 125.23 Language, voice and interface design Interface language can determine economic access. A user may understand Maithili, Angika or another local speech form far better than formal Hindi or English but encounter payment menus, fraud warnings and grievance procedures only in larger languages. Voice interfaces and conversational payment systems can lower literacy barriers, while poorly designed transliteration can create new confusion. Local-language support is especially important for confirmation messages: the user must understand the payee, amount and action before authentication. The challenge is not merely translation but terminology, script support, speech recognition and accessibility. A digitally sophisticated region can still exclude users if the interface assumes a linguistic competence different from the language of everyday commerce. 125.24 Fraud, impersonation and cyber risk Digital payment growth expands the attack surface for fraud. Criminals can exploit remote-access applications, false customer-care numbers, deceptive QR codes, phishing links, SIM swaps, social engineering and requests to ‘receive’ money by entering a PIN. The victim often experiences the fraud as a communication event before it becomes a banking event. This makes telecom regulation, platform moderation, bank controls and public awareness part of the same security system. Nepal Rastra Bank’s August 2026 warnings about fraudulent accounts and QR codes for relief contributions illustrate the continuing relevance of basic verification even in a mature QR environment. Fraud data should be analysed by method and loss, not only by number of complaints. 125.25 Failed payments, reversals and grievance redress Trust in instant payments depends on what happens when the payment is not instant in practice. A debit can occur without merchant confirmation; a reversal can take time; the user may contact the bank, payment app and merchant separately; and low-value disputes can impose high time costs. RBI’s payment regulation, ombudsman mechanisms and transaction-failure rules are therefore part of economic infrastructure. Merchants likewise need predictable settlement and clear refund procedures. For regional fieldwork, failed- payment diaries are more informative than simple adoption questions because they reveal whether users return to cash after a bad experience. Consumer protection is a productive input: without credible redress, technically available payment rails may be underused. 125.26 Nepal’s mobile-banking, wallet and QR ecosystem Nepal’s payment ecosystem has developed through banks, wallets, payment service providers, QR networks and the national clearing infrastructure. Nepal Rastra Bank’s payment-system indicators show rapid growth of mobile banking, wallets and QR-based payments, while its oversight reports emphasise interoperability, cyber resilience and regulation of licensed operators. The relevant comparison with India is not a race for identical transaction volumes. Nepal’s smaller market, different banking structure and remittance dependence produce a distinct institutional path. Madhesh participates in this national system through merchants, banks, migrant households and cross-border travellers. Local studies should therefore HISTORY OF MITHILA, VAJJI & ANGA — VOLUME II connect NRB’s national indicators with province- and municipality-level evidence rather than infer Madhesh usage directly from national totals. 125.27 The India–Nepal cross-border payment corridor The India–Nepal corridor now has two separate digital-payment milestones. From February–March 2024, UPI users from India could make person-to-merchant payments at participating Nepalese QR merchants; NPCI reported more than 100,000 such transactions by August 2024. In June 2026, a direct UPI–NPI linkage was operationalised for real-time person-to-person remittances through select banks and apps. The distinction is crucial: buying goods in Janakpur is not the same transaction as sending household support across the border. The new P2P rail can reduce time and reliance on intermediaries, but foreign- exchange rules, limits, KYC, fraud control and participating-institution coverage still shape actual use. Border digitalisation therefore formalises some flows without making the border economically irrelevant. Figure 498 — India–Nepal payment integration developed in distinct stages: merchant UPI acceptance in Nepal from 2024 and bilateral P2P UPI–NPI remittance from June 2026. 125.28 Data governance, privacy and exclusion Digital systems generate valuable data and new risks. Transaction records can improve fraud detection, credit assessment and economic measurement; location and behavioural data can also reveal intimate patterns of movement, consumption and work. Platform workers may have little bargaining power over data collection, while small merchants may not know how ranking or recommendation systems use their activity. Exclusion can arise through false fraud flags, KYC mismatch, inactive numbers or automated risk scores. Data governance is therefore part of distributive economics. The historian should ask who can see the data, who can correct it, how long it is retained and whether the person whose activity generated it can obtain a usable record. 125.29 Building an evidence archive for digital economic history Born-digital economic evidence is unusually fragile. Payment apps update interfaces without preserving public archives; merchant listings disappear; platform commission schedules change; worker incentive screens are personalised; and transaction dashboards may provide only current aggregates. A serious archive for this chapter’s subject should preserve dated regulator reports, NPCI and NRB series, telecom indicators, labour notifications, platform terms, screenshots, anonymised merchant statements and worker diaries. 12831283 GAJENDRA THAKUR Researchers must record denominators and geographies: a telecom service area may span two states, a national UPI total cannot be assigned to one district, and platform registrations may lag actual work. Metadata is therefore not clerical detail but protection against false precision. 125.30 From digital coordination to destination economies Digital payments and mobile platforms now coordinate a substantial share of the journeys, purchases and services described across PART XIII. They shorten payment time, widen market reach and make transactions traceable, while shifting new forms of operational and informational risk onto users, workers and merchants. Their regional impact is strongest where physical connectivity, financial institutions and digital capability reinforce one another. The next chapter, on tourism and pilgrimage economies, makes this interdependence visible: travellers discover destinations on phones, book transport online, navigate by map, pay merchants by QR and increasingly cross the India–Nepal border through interoperable payment systems. Digital coordination does not replace place; it changes how places are reached, consumed and economically connected.
