Today UPI is very popular. You can make UPI Payments in the smallest shops. It is everywhere. In September 2022 ₹ 11.2 Lakh Crore was transacted through the UPI.
1. Full Form of The UPI
The full form of the UPI is the Unified Payment interface. This interface facilitates the money transfer between two bank accounts. This money transfer itself has many easy ways. You can choose a mobile number, QR code, and UPI ID to make a payment. There is too much flexibility. That is why people have lapped the Unified Payment Interface.

2. Why UPI is Popular – Advantages
Cash hai to aish hai. You Have been using cash for ages. It has been the dominant payment system, but no more. UPI has overtaken all other forms of payment. In fact, UPI Has many benefits over other payment systems.
1. Very Easy to pay
UPI has many ways of payment. You can choose one according to the situation. You can use the mobile number of the payee if paying your family and friend. You can scan a QR code if paying to a merchant. You can approve payment requests if shopping online.

2. Quick
The payment through the UPI takes a few seconds. The money transfer takes place immediately. Today, you can see that in a shop, if you use the UPI, the payment process would take less than a minute. Whereas cash payment takes more time than this unless you have the exact amount.
3. Hasslefree
Cash payment has its own hassle. As you have to carry cash. The currency can mutilate in the pocket. It can also drop. Moreover, sometimes you may not have the proper change. This can result in a wait unless the shopkeeper arranges the change.
But, in the case of the UPI payment, there is no such hassle. If you have money in your account, you can pay it immediately without thinking twice.
4. Keeps Record
The UPI payments are recorded in your bank statement. Thus you can always refer in future if required. You can also track your expenses because of the records.
It is not possible with cash. We rarely remember all of our cash payments.
5. Cash Withdrawal is Not Required
To make cash payments, we need cash at our disposal. Thus we have to withdraw cash either from the ATM or Bank. It is a hassle and sometimes takes plenty of time.
If you are using UPI for payments, your visit to the ATM or bank would be rarer.
6. Free
UPI gives us many conveniences. But It does not ask for anything in return. The government has kept it free. There are no charges for UPI Payments whether it is a small amount or a large amounts.
3. Requirements For UPI
UPI is prevalent. You would have seen that almost every second person uses this method of payment. To use this method of payment, you need the following things.
i. Bank Account
This system of payment uses your bank account for making payments. In this system, money goes from one bank account to another bank account. Thus the payer and payee both must have a bank account.
ii. Debit Card / ATM card
The payment takes place between the bank account. But for authentication, you need a debit card. In fact, This system requires UPI PIN for making a payment. But this PIN can’t be set without the debit card details. Thus, to set the UPI PIN, you need a debit / ATM card. However, few banks have started the facility of aadhaar authentication to set the UPI PIN. Thus you can use UPI PIN without a debit card. These banks are Canara Bank and Union Bank.
iii. Smartphone
Although the UPI system works in feature phones (you can dial *99# to use UPI). But using a feature phone is not very convenient. UPI is very easy with the smartphone. In the smartphone, you can have one of the UPI apps. Phonepe, Paytm, and Google Pay are such apps.
iv. Balance in the Account
You also need money in your bank account. You can check your account balance through the UPI app itself.
4. Steps to Use
- To use the UPI payment system, you must install at least one of the UPI apps. There is a long list of UPI apps. Almost every bank has its own app. Besides this, there are many third-party UPI apps.
Today, third-party apps are the most popular. For example Phonepe, Google Pay, Paytm, Mobikwik and Amazon Pay. These are third-party apps and are very popular.
- After installing the UPI app, you have to link your bank account. You can do this by selecting your bank from the given list. Once you select a bank, the system finds out your account in that very bank.
As your bank account gets linked, you would be able to receive money in your bank account. But to make a payment, you have to also set the UPI PIN.
- To set the UPI PIN of a bank account, you must have the debit card of that bank account. The debit card details are entered to set the UPI PIN. You have to also enter OTP which is sent to your registered mobile.
Note, you must use the same sim (mobile number) which is registered with your bank account.
The UPI PIN can be either 4 digits or 6 digits. It depends upon the bank. The SBI uses 6 digits PIN. You must remember this PIN to use it further.
- After setting the UPI PIN, you can make payments using your preferred way. It can be a QR code, mobile number, UPI ID or Bank account detail.

7. UPI Charges
As I have said earlier UPI system does not charge a paisa for this facility. In this system, 3 parties are involved these are NPCI (manages UPI system), Banks (transfers money from one account to another) and apps (provides an interface for UPI system).
But as of now none of them charges for the service. The government is trying to make this system always free. The involved parties can recover their cost through other means.
8. Problems of UPI
The UPI Payment system has leapfrogged very swiftly. today millions of transactions take place in a day. Some of the banks were not ready for this heavy load.
In fact, banks have to maintain secure servers to deal with these transactions. But, some banks could not cope with heavy demand. This resulted in failed transactions. The money gets debited but not credited to the beneficiary account.
However, the users usually get back their money within 3 working days. still, it is a headache. Lately, such instances have come down. People also get back their money within a few hours.
The RBI has also introduced the services of Digisathi to deal with UPI-related complaints.
