The National Payments Corporation of India (NPCI) introduced the Unified Payments Interface (UPI) as a new, real-time bank-to-bank payment system for mobile devices. UPI’s design allowed payments using a virtual payment address (VPA) instead of sharing bank account details, making everyday digital transfers simpler. This launch set the foundation for later policy and regulatory steps to expand adoption and manage risks at national scale.
The government-backed BHIM (Bharat Interface for Money) app was launched to give the public a simple, standardized way to use UPI. By providing an official, easy-to-understand interface for sending and receiving money, BHIM helped make UPI more accessible beyond early bank apps and tech-forward users. The launch also signaled strong political and administrative support for a nationwide digital payments push.
To speed up adoption, the government launched referral incentives for BHIM users to bring new people onto the platform. Incentives can be a policy tool to overcome early hesitation by users and merchants, especially when cash is still common. This period helped normalize UPI as an everyday payment option rather than a niche technology.
The Reserve Bank of India (RBI) issued the circular "Storage of Payment System Data," requiring payment system operators to store payment data in India. The goal was to improve supervisory access and oversight for a rapidly growing digital payments ecosystem. This requirement became an important compliance theme for UPI-linked players, including large technology firms entering payments.
NPCI launched UPI 2.0, adding features intended to support broader merchant use and stronger customer protections. These included options like signed intent/QR (to reduce QR tampering) and invoice-in-the-inbox (to help users verify what they are paying for). UPI 2.0 signaled a shift from “basic transfers” toward a more full-featured payments platform that could handle more complex purchase flows.
RBI’s six-month deadline for payment data localization reached its end, turning the policy into an enforceable expectation rather than a future goal. This compliance milestone mattered because it pushed payment operators to invest in domestic storage and auditing processes. It also influenced how new UPI participants planned their infrastructure and rollout strategies.
UPI crossed a major scale milestone: more than one billion transactions in October 2019, according to NPCI’s reporting. Hitting this level showed that UPI was no longer an experiment and had become a core national retail payments rail. The growth also increased the need for clear rules on costs, data practices, and responsibilities across banks and fintech apps.
RBI communicated that WhatsApp Pay would not be allowed to fully roll out on UPI unless it met payment data localization requirements. This highlighted that UPI access for large platforms depended on regulatory compliance, not just technical integration. The episode became a visible example of how policy decisions shaped who could scale on India’s national payments infrastructure.
The government prescribed electronic modes for businesses to offer—specifically including UPI and RuPay—through an official notification. This policy supported a “less-cash” economy by pushing large businesses to provide convenient digital acceptance options. It also connected UPI adoption to broader compliance requirements in the tax and payments legal framework.
Rule 119AA became applicable from January 1, 2020, specifying UPI and RuPay (and related QR modes) as prescribed electronic modes for certain businesses. Alongside this framework, Section 10A of the Payment and Settlement Systems Act provided that no charge should be imposed on payer or beneficiary for these prescribed modes, reinforcing “zero MDR” expectations for UPI/RuPay acceptance. This was a major policy turning point that supported scale-up but also raised questions about long-term funding of payment infrastructure.
RBI issued guidelines to regulate payment aggregators and payment gateways, clarifying roles and compliance expectations for intermediaries that collect payments from customers and settle them to merchants. While not UPI-only, these rules affected many merchants and fintechs that offered UPI as one of the payment methods they routed. The policy aimed to reduce risk in fast-growing digital commerce by setting clearer standards for onboarding, escrow/settlement practices, and oversight.
NPCI introduced UPI AutoPay to support recurring payments through e-mandates (for example, subscriptions or utility bills). This moved UPI beyond one-time transfers into scheduled, repeat payments, which typically require stronger consumer protections and clear authorization steps. AutoPay became a key capability for scaling digital services while keeping recurring debits more controlled and transparent.
The approved incentive scheme took effect from April 1, 2021, providing operational support for ongoing UPI expansion in merchant payments. By this stage, UPI had moved from “rollout” to “system maintenance at national scale,” where policy choices needed to balance growth, user cost, and sustainability for banks and payment providers. The effective date marks a clear endpoint for the 2016–2021 rollout phase: UPI was mainstream, and government policy shifted toward sustaining and deepening usage.
The Union Cabinet approved an incentive scheme aimed at promoting RuPay debit card and low-value BHIM-UPI person-to-merchant transactions. The scheme was designed to support acceptance even when merchant fees were expected to be zero, by paying incentives to acquiring banks. This step addressed a practical rollout challenge: scaling UPI for small merchants while keeping costs low for end users.
