UPI Payments

A brief explanation.

Unified Payments Interface

Introduction

NPCI (National Payments Corporation of India) a not-for-profit organization functions under RBI (Reserve Bank of India) and IBA (Indian Bank Association). It was launched in 2008 with an aim to handle and transform payments in India.

One of the prominent services of NPCI includes payments through UPI, launched in 2016 (the same year Demonetisation happened).

UPI (Unified Payment Interface) is a payment system built on IMPS technology to enable instant transfer of money between bank accounts using a VPA (Virtual Payment Address)or UPI id without having to use bank account or debit/credit card details.

There was clearly a large scope in retail payments to be digitized across after UPI’s launch since it enabled a large base of payer and payee to get onboard. Imagine one being a small merchant, wouldn’t be comfortable in sharing their bank account details with you for a nominal transaction but instead, a mobile number or an email id wouldn’t be much big of a deal with also saving you from that “cash change hassle”.

UPI 2.0

NPCI (National Payments Corporation of India) launched an upgraded version of UPI in August 2018 — UPI 2.0. UPI 2.0 has emphasized more on peer-to-merchant spheres, unlike the previous version which focused on peer-to-peer transaction base. This approach has unleashed enormous opportunities for small and big merchants to shift from the traditional POS system to a contactless POS system. This is the reason why banks are facing disruption in their POS device business. At the time of the launch UPI 2.0 was supported by 11 banks.
