However, USSD banking does not give the bill payment facility.

The good feature of UPI is that bank account number is not required for payment. You can use a virtual Payment address instead of the bank account. One can send money to your VPA and you would receive it into the bank account.
When you use this app the first time, it asks you to set the UPI ID. You set the ID of your choice. The process is similar to the Email address selection. You can learn more in my detailed post about the UPI ID.
iii. Link Bank Account
Once, you give permission to use messaging, the UPI app sends an SMS to the server. On the basis of this SMS, the system finds out your mobile number.
The mobile number is again used to find out those bank accounts which are linked to the number. Through this process, the UPI server ascertains your linked bank account number.
After the registration, you have to link a bank account to the app. This process has two steps.
- Choose You bank from the list. There are 58 banks which support this system. All, big banks are part of it.
- If you have more than one account in a bank, you would see the account number of both the account. You should choose the desired account.
You can add all of your bank accounts. However, You have to choose one default bank account. This account would be used to send and receive money. If you want to change the account, you must change the default account. It is one tap process.
iv. Set UPI PIN
You can not directly pay from your bank account. Rather, you need to authenticate before the payment. This authentication is necessary for security so that no one can misuse your app.
- This authentication is done through the UPI PIN. It is a 4-6 digit PIN which is required whenever you pay to someone. Your every Bank Account would have its own UPI PIN. You must use PIN accordingly.
- You can generate or reset PIN from the app itself. To generate the PIN, you have to enter last 6 digits of your debit card number and validity of the card in MM/YY format.

7. Best UPI Apps
There are several UPI app available. You can use any of them. Each app has basic features but you would experience some difference. The BHIM has upped the bar very high.
UPI apps are competing to give you the best experience. I have also tried many apps to find out the best one. These are the best one.
Google Pay (TEZ)

As evident from the name, this app is developed by Google. This app is relatively new as it came almost 9 months after the BHIM and other apps. However, It has become quite popular because of it simple and focused approach. Google has partnered with 4 banks to give UPI services. You can choose any of the 4 banks for the transactions.
The Google Pay (Tez) has a unique feature ‘Cash Mode’. In this mode, you can very easily send money to a nearby person. It works like the Shareit app. The Tez is also giving you the bill payment facility.
The popularity of Tez app is also due to its reward program.
Phonepe

It is one of the oldest UPI app. This app is very convenient and feature-rich. The app is promoted by the Flipkart. It gives discounts as well if you pay through the Phonepe. This app also works as a mobile wallet. You can recharge your mobile through this app. This app also gives facility to pay the bill for electricity, water, gas and DTH. Recently, Phoenpe has started selling digital gold through it.
Paytm

Paytm has almost become a synonym for the mobile payments. You can see a Paytm QR code at many shops. However, It has been a mobile wallet. It has promoted its wallet heavily. However, The ease of UPI forced Paytm to embrace it. Now Paytm also supports this payment. The Paytm has launched its own Payment bank the Paytm Bank.
Like its original wallet, UPI payment through the Paytm is also very easy. People easily recognise this app hence, it is easier to pay at merchant shops using UPI payment of Paytm. However, sometimes the clutter of a shopping site irritates us. The Paytm also sell products through this app.
SBI Pay

The SBI Pay is now BHIM SBI Pay. This app is launched by the SBI. It is also one of the oldest UPI apps. Since then, SBI has modified it many times. Now it is sleek and easy. It is very easy to check account balance through the SBI Pay. It has only basic features but very user-friendly. However, sometimes it gets slow.
BHIM

It is the game changer app. After the launch of BHIM, we get to know that how easy a financial app can be. This is the app which taught mobile banking to most of the people. Till date, it is one of the easiest and simple apps.
The BHIM is developed by the NPCI itself. Initially, the government of India has promoted it. To encash its popularity, the NPCI has added BHIM word to the UPI system. It has also advised the banks to use BHIM word with their UPI app. Many banks have endorsed this. You can see BHIM Baroda Pay, BHIM SBI Pay, BHIM axis Pay etc. However, Lately, this app is losing the market share.
In this post, I have told you about the UPI Payment system and how it works. Today, it has become the preferred mode of fund transfer. However, NEFT, RTGS and IMPS are still useful. You should also learn about them.
