UPI full form: Unified Payments Interface

How to say it: letter by letter.

UPI stands for Unified Payments Interface. It is the instant payment system that lets you send money from your bank account to another person's bank account using a mobile phone, at any hour of any day.

Who runs it

UPI was developed by the National Payments Corporation of India, NPCI, and is regulated by the Reserve Bank of India. It was launched in 2016. Apps such as BHIM, and the payment apps of banks and other companies, all work on the same UPI system, which is why a person using one app can pay a person using another.

The words used in UPI

• UPI ID or VPA (Virtual Payment Address): an address such as name@bank that stands in for your account number.
• UPI PIN: the secret 4 or 6 digit number you set yourself and type to approve each payment.
• QR code: Quick Response code, the square pattern a shop displays for you to scan.
• UTR: the reference number of a completed payment.
• Collect request: a request for money sent to you by someone else, which you approve or decline.

The one rule that prevents most fraud

You type your UPI PIN only to send money. You never need a PIN, a QR scan or an OTP to receive money. If someone tells you to scan a code or enter your PIN in order to get a refund, a prize or a payment, it is a fraud: stop. Never share your PIN or OTP with anyone.

If something goes wrong

For a failed payment where money has left your account, first use the help or dispute option inside your app, then contact your bank. To report a financial fraud in India, call the national cyber crime helpline or use the official cyber crime portal as quickly as possible.
