How money actually moves between bank accounts in India in seconds or hours โ and which payment rail to use for which situation.
A payment system is the infrastructure that moves funds from a payer's bank account to a payee's โ instructing, clearing, and settling the transaction between banks. India runs several parallel systems, each engineered for a different combination of speed, value and availability.
| System | Settlement | Typical Limit | Availability | Best For |
|---|---|---|---|---|
| NEFT | Batch, half-hourly | No RBI-mandated cap (bank-set) | 24x7x365 | Routine transfers, salary/vendor payments |
| RTGS | Real-time, gross (transaction-by-transaction) | Minimum โน2 lakh, no upper cap | 24x7x365 | Large-value, time-critical transfers |
| IMPS | Real-time, individual | Up to โน5 lakh per transaction (bank-set) | 24x7x365 | Instant person-to-person transfers |
| UPI | Real-time, individual | Up to โน1-5 lakh (use-case dependent) | 24x7x365 | Everyday retail/merchant payments via mobile |
The National Payments Corporation of India (NPCI), set up under the guidance of RBI and IBA, operates the retail payment infrastructure for the whole country. Its key products beyond UPI and IMPS include:
India's own domestic card network, an alternative to Visa/Mastercard.
National Automated Clearing House for bulk debit/credit (EMI, dividend, salary).
Bharat Bill Payment System โ a single interoperable platform for utility bill payments.
Aadhaar-enabled Payment System for basic banking via biometric authentication.
Cheque Truncation System โ see the dedicated Clearing guide.
Extends UPI acceptance to select countries for outbound Indian travellers.
RBI mandates two-factor authentication (2FA) for all digital transactions (PIN/OTP plus device binding for UPI), and card payments rely on tokenisation โ replacing the actual card number stored with merchants by a unique token, so the real card details are never held on a merchant's server. Banks are also required to run real-time fraud-monitoring systems and offer zero-liability/limited-liability protection to customers who report unauthorised transactions promptly.
The eโน (Digital Rupee) is RBI's Central Bank Digital Currency, issued as a direct liability of RBI (unlike UPI/bank money, which is a liability of the issuing bank). It exists in a Retail (eโน-R) pilot for general public use and a Wholesale (eโน-W) pilot for interbank settlement, and is being expanded gradually rather than replacing existing payment rails.
