Wallet Interoperability

Wallet interoperability lets full-KYC prepaid wallets transact with each other and with bank accounts through UPI, so money is not locked within a single provider's ecosystem.

Wallet interoperability means a balance in one full-KYC PPI wallet can be used to pay merchants and individuals across providers and bank accounts, primarily by enabling UPI on wallets, rather than being usable only within that wallet's closed loop.

RBI mandated interoperability for full-KYC wallets to break silos and improve user choice. Small (minimum-KYC) wallets have tighter restrictions and may not be fully interoperable.

For users, interoperability increases the utility of wallet balances and reduces lock-in. It is a key step in integrating prepaid instruments into the broader UPI payments network.
