Everything You Need to Know about Unified Payments Interface (UPI) – liveinsure.in

Posted on

The unified payments interface or the UPI is an interface via which you can transfer money between bank accounts across a single window. This means you can send or receive money or scan a quick response (QR) code to pay an individual, a merchant or a service provider to shop, pay bills or authorise payments.

To enable payment using your phone, all you need is a mobile payment application and the virtual address of the payee (that reads something like merawalashop@xyzbank). This implies you can make payments directly to the accounts of a vendor or a person, in one step. There is no repetitive step involved. For example, entering bank details or other sensitive information each time you need to make a payment.

It is simple, free of charge and instantaneous. UPI allows you to make transactions 24/7, throughout the year. Currently, one can transfer upto INR 1 lakh in a single UPI transaction.

UPI was launched in 2016, is the brainchild of the National Payments Corporation of India (NPCI), the umbrella organisation that oversees retail payment systems in India. The NPCI is governed by the central banking authority, the Reserve Bank of India, and its primary goal is to drive India towards becoming a digital economy.

What Is a Unified Payment Interface (UPI)?

A Unified Payment Interface (UPI) is a smartphone application that allows users to transfer money between bank accounts. It is a single-window mobile payment system developed by the National Payments Corporation of India (NPCI). It eliminates the need to enter bank details or other sensitive information each time a customer initiates a transaction.

The Unified Payment Interface is a real-time payment system. It is designed to enable peer-to-peer inter-bank transfers through a single two-click factor authentication process. The interface is regulated by the Reserve Bank of India (RBI), India’s central bank. It works by transferring money between two bank accounts along with a mobile platform.

The system is said to be a safe and secure method of transferring money between two parties and eliminates the need to transact with physical cash or through a bank. The pilot system was launched in India on April 11, 2016. Banks across the country started to upload their interface in August 2016.

Who initiated UPI?

UPI is an initiative taken by the National Payments Corporation of India (NPCI) together with the Reserve Bank of India and Indian Banks Association (IBA). NPCI is the firm that handles RuPay payments infrastructure, i.e. similar to Visa and MasterCard. It allows different banks to interconnect and transfer funds.

What is UPI ID and PIN?

A UPI ID is a unique identification for a bank account that can be used to send and receive funds. UPI PIN is a 4-digit personal identification number that must be entered to authorise the transfer of money via UPI. The PIN can be chosen by the account holder.

Your VPA is unique and flexible

You may wonder that if your smartphone’s VPA is maliciously being used in another system, your financial security could be compromised. This is not the case as the VPA is not permanent. A service provider can offer you an address that expires after a single use.

Alternatively, you can get an address that is restricted to limited use. The address can be used for transacting a fixed amount of money or for a pre-defined time. The address can also be bound to specific payees, which means that other users cannot transact with you. The service provider can create as many VPAs as you want. Customized authorizations can be assigned to each of them.

What is the level of security in UPI?

UPI has a single click-two factor authentication system which means that with one click the transaction is authenticated at two levels. The user will need a mobile phone with a mobile pin called MPIN and a virtual ID offered by the provider. With a click the transaction is checked if the mobile pin matches with the virtual address only then does the transaction goes through.

Here is an example to explain the process.

Suppose you have bought some goods at a mall and need to make a payment for it. You have to inform your virtual address to the person at the counter who enters the address in his or her system. The mall’s system then sends an authentication message to the virtual address which is mapped to your mobile. Only after receiving the message and acknowledging it by entering your password is the transaction complete and the amount debited from your bank account or wallet.
