Prepaid Payment Instruments (PPIs) are a convenient way for users to keep their money stored digitally and make purchases for various goods, services, remittances, and financial services. In India, PPIs are divided into three main categories:
Closed System PPIs
These can only be used within the issuer’s own ecosystem, like gift cards from a specific brand.
You can't make third-party payments or withdraw cash with these.
No approval from the RBI is needed since they aren't considered a payment system.
Semi-Closed System PPIs
These are accepted at a network of pre-approved merchants, such as digital wallets and food delivery apps.
Cash withdrawals aren't allowed, no matter if the issuer is a bank or a non-bank.
They require agreements with merchants through payment aggregators or gateways.
Open System PPIs
Only banks can issue these, and they can be used at any merchant or service provider.
They allow for cash withdrawals at ATMs, PoS, and through Business Correspondents (BCs).
This type offers more flexibility and promotes financial inclusion.

RBI Guidelines on PPI Escrow Accounts
To keep things secure and compliant, the Reserve Bank of India (RBI) requires that all non-bank PPI issuers hold their outstanding balances in an escrow account with a scheduled commercial bank.
Escrow Account Requirement
The balance in the escrow account should never dip below the total outstanding PPI amount by the end of each day.
Quick Fund Transfer
PPI issuers are required to deposit funds into the escrow account on the same business day to ensure transparency and security.
Regulatory Supervision
According to Section 23A of the PSS Act, 2007, non-bank PPI operations are recognized as ‘designated payment systems’, which means they are closely monitored by the RBI.
This Escrow setup safeguards consumer funds, facilitates smooth fund settlements, and bolsters the stability of the financial system.
