India: UPI & Regulatory Masterclass

The Undisputed King: UPI

Developed by the National Payments Corporation of India (NPCI), the Unified Payments Interface (UPI) processes over 10 billion transactions per month. It allows users to link multiple bank accounts into a single mobile application (like PhonePe, Google Pay, or Paytm) and instantly transfer funds using a Virtual Payment Address (VPA).

If you are an international merchant trying to sell digital goods or SaaS in India without supporting UPI via local acquiring, your conversion rate will likely hover below 15%. UPI is mandatory.

RuPay: The Domestic Card Network

RuPay is India's domestic card payment network, formulated to compete with Visa and Mastercard. With zero Merchant Discount Rates (MDR) mandated by the government for certain transaction tiers, RuPay debit cards are the default issuance for the vast majority of the Indian population outside of metropolitan hubs.

Routing RuPay transactions through an international payment gateway is impossible; it requires a deep integration with an Indian acquiring bank.

Reserve Bank of India (RBI) Strictures

The RBI is one of the most proactive and stringent financial regulators in the world. Operating in India requires absolute adherence to two massive mandates over the last three years:

• Tokenization (COF): As of late 2022, merchants and payment gateways can no longer store raw credit card data (Card-on-File) for Indian consumers. All cards must be tokenized at the network level. Our Token Vault Integration abstracts this compliance entirely.
• e-Mandates for Recurring Billing: Automatic subscription renewals on credit cards or UPI require a strict AFA (Additional Factor of Authentication) for the first transaction, and any subsequent transaction over ₹15,000 requires explicit user approval via an OTP every single time.
