What is UPI and Why It Matters
The full form of UPI is Unified Payment Interface. It is an instant payment system developed by the National Payments Corporation of India (NPCI).

How Does UPI Work? Step-by-Step Process
You need to register the UPI app with the mobile number linked to your bank account. Then you need to select your bank and create a virtual payment address (VPA) to which the money will be transferred. For example, yourname@bankname.
Here’s a step-by-step breakdown of how UPI works:
- Linking a mobile number
To use the UPI system, you must first link your mobile number to your bank account. - App download and registration
To use UPI, you need to download a UPI-enabled app such as Google Pay, PhonePe, Paytm, BHIM, etc. and register the app with the mobile number linked to the bank. - Adding a bank account
After registration, you will need to select your bank and add your bank. - Create a UPI ID
You need to create a UPI ID or virtual payment address. For example, yourbank@bankname. You can send or receive money using this UPI ID. However, this UPI ID is automatically created after registration. You can create a new ID if you want. - Setting UPI pin
For security, a UPI PIN must be set, usually 4-6 digits. No transaction will be completed without this PIN, and for security, this PIN should not be disclosed to anyone else. - Start a transaction
Once everything is set up, you can send money, pay bills, and do any kind of recharge, all from your mobile.

UPI vs Traditional Banking
There are several differences between UPI vs traditional banking. For example, through the UPI system, you can transact money from home. But in the case of traditional banking, you have to go to the bank to transact money.

| Cost | Mostly free | Service charges apply |
| Availability | 24×7 | Limited banking hours |
