As per the road-map laid down in 2017, interoperability of all KYC-compliant Prepaid Payment Instruments (PPIs) was to be enabled in three phases – interoperability of PPIs issued in the form of wallets through Unified Payments Interface (UPI), interoperability between wallets and bank accounts through UPI, and interoperability for PPIs issued in the form of cards through card networks.
The Reserve Bank of India (RBI) issued consolidated guidelines for enabling all phases “in order to prepare better for implementation of interoperability”. Interoperability is the technical compatibility that enables a payment system to be used in conjunction with other payment systems.
Interoperability allows PPI issuers, system providers and system participants in different systems to undertake, clear and settle payment transactions across systems without participating in multiple systems. MobiKwik, Oxigen, Paytm, ItzCash, and Ola Money are some of the popular mobile wallets in the country. Currently, a mobile wallet does not allow customers to send or receive money from a wallet run by another company.
