Unlocking the Power of UPI: A Comprehensive Guide to Unified Payments Interface

on

Introduction

I recently visited my family back in India and was awestruck by my experience and this compelled me to share about this fascinating transaction system called UPI.

This is from my recent personal experiences -

more than 100 transactions in a month. The total value of transactions close to 200K.

Filling gas, hiring cab or rickshaw, purchasing sweets. Received payment from friends.

Restaurant, ice cream shop , food truck you name it. The experience of making any transaction was smooth as silk.

One fun fact 😊 , you should still carry some cash in case a rickshaw driver doesn’t accept UPI payments. It’s hard to find one but I did find a couple who didn’t.

UPI – Unified Payment Interface was first introduced in 2016 with just 21 banks and had almost 0 transactions for straight 3 months and is now leading the chart globally.

From April 2016 to August 2022, the graph has significantly changed, now there are above 345 Banks live on UPI and a total number of transactions has crossed 10,72,792 crores (as of August 2022) and this figure itself is proof that how people have become adaptive on making more and more cashless UPI payments.


What is UPI?


UPI payment, which stands for Unified Payments Interface, is an Indian instant payment system and protocol developed by the National Payments Corporation of India (NPCI) in 2016. Here are the key points about UPI:

  1. Purpose: UPI facilitates inter-bank peer-to-peer (P2P) and person-to-merchant (P2M) transactions. It allows users to instantly transfer funds between two bank accounts using their mobile devices.
  2. Simplified Process: Unlike traditional methods that require detailed banking information, UPI simplifies transactions. Users can transfer money using just the UPI ID (Virtual Payment Address) of the recipient.
  3. Mobile Number Registration: The mobile number associated with the device needs to be registered with the bank to use UPI.
  4. Open Source API: UPI runs as an open-source application programming interface (API) on top of the Immediate Payment Service (IMPS) and is regulated by the Reserve Bank of India (RBI).
  5. Growth and Usage:
    • India leads in instant payments globally, accounting for 46% of all such transactions in 2022.
    • UPI had over 300 million monthly active users in India as of November 2022.
    • The proportion of UPI transactions in total digital transactions grew from 23% in 2018–19 to 55% in 2020–21.
    • It enabled over 2,348 transactions every second in 2022.
    • In January 2024, 12.20 billion UPI transactions worth ₹18.41 lakh crore (equivalent to $222.17 billion) were processed, representing a significant increase compared to the previous year.
    • The total annual value of UPI transactions in India reached ₹182 lakh crore (equivalent to $2.2 trillion) in 2023, reflecting substantial growth.

UPI has revolutionised digital payments in India, making it a powerful tool for financial inclusion and convenience.

How does it work?


Let me explain how UPI (Unified Payments Interface) works:

  1. Registration:
    • To use UPI, you need to have a bank account with a bank that supports UPI transactions.
    • Download a UPI-enabled mobile app (such as Google Pay, PhonePe, or Paytm).
    • Link your bank account to the app by providing your mobile number registered with the bank.
    • Set up a Virtual Payment Address (VPA), which acts as your unique UPI ID (e.g., yourname@bankname).
  2. Transaction Process:
    • When you want to make a payment or transfer money, follow these steps:
      • Open the UPI app on your smartphone.
      • Choose the option to send money or make a payment.
      • Enter the recipient's VPA (or select from your contacts).
      • Specify the amount you want to transfer.
      • Verify the details and confirm the transaction using your UPI PIN (set during registration).
  3. UPI ID and VPA:
    • Your VPA (UPI ID) is like an email address for money. It replaces the need to share bank account numbers and IFSC codes.
    • For example, if your VPA is "yourname@bankname," anyone can send money to you using this ID.
  4. Immediate Settlement:
    • UPI transactions are settled instantly. The money moves directly from your bank account to the recipient's account.
    • It works 24/7, including weekends and holidays.
  5. Security Measures:
    • UPI uses two-factor authentication: your mobile number and the UPI PIN.
    • The UPI PIN is required for every transaction, ensuring security.
    • UPI also supports biometric authentication (fingerprint or face recognition) for added safety.
  6. Types of Transactions:
    • P2P (Person-to-Person): Transfer money to friends, family, or anyone with a UPI ID.
    • P2M (Person-to-Merchant): Pay at shops, restaurants, or online stores by scanning QR codes.
    • Bill Payments: Settle bills for utilities, mobile recharges, and more.
  7. QR Code Payments:
    • Many merchants display QR codes (Quick Response codes) at their shops.
    • You can scan these QR codes using your UPI app to make payments directly.
  8. Bank Agnostic:
    • UPI is not tied to any specific bank. You can use any UPI-enabled app with any bank account.

Remember that UPI has transformed digital payments in India, making them faster, more convenient, and secure.

    • Sometimes, UPI transactions can be delayed due to network or bank server issues. This can hinder the payment process.
    • If a transaction fails, the deducted money may take up to 48 hours to be credited back to your account².
  2. PIN Security:
    • UPI relies on a 6-digit PIN for authentication. While convenient, this PIN might not be as strong as longer passwords or biometric methods.
    • Users should choose a secure PIN and avoid sharing it with anyone.
  3. Dependency on Technology:
    • UPI transactions depend on digital infrastructure and internet connectivity.
    • Power outages, natural disasters, or disruptions in connectivity could impact UPI services.

    • UPI is currently available only in India. Users outside the country do not have access to this payment system⁴.
  5. Transaction Reversals:
    • Although rare, incorrect transactions or fraudulent activities can occur.
    • If you accidentally transfer money to the wrong recipient, reversing the transaction may involve additional steps and coordination with the bank.
  6. Privacy Concerns:
    • While UPI ensures privacy by using virtual addresses (VPAs) instead of sharing sensitive information, users should still be cautious.
    • Ensure that your VPA is not easily guessable or linked to personal details.

Remember that being informed about these aspects helps you make better decisions while using UPI. Overall, UPI remains a convenient and widely used digital payment system in India, but like any financial tool, it's essential to use it wisely and securely!
