You may have seen a square barcode, often on merchant counters or payment terminals, which allows instant digital payments.
That pixelated square is called a QR code. In the context of UPI, these dynamic QR codes enable seamless, contactless, and real-time payments from any UPI-enabled app.
Although QR codes were invented in the mid-1990s, their widespread use in India skyrocketed with the introduction of UPI and the growing smartphone adoption. UPI Dynamic QR codes empower merchants by allowing flexible transaction amounts, secure payments, and easy reconciliation.
Here’s everything you need to know about UPI dynamic QR codes and how they work.
Invented in 1994 by Masahiro Hara of Denso Wave, QR codes were originally designed for tracking parts in manufacturing. Today, dynamic QR codes, especially in the UPI ecosystem, provide an efficient and safe way to transfer money instantly.
“Quick Response” (QR) codes store data as a matrix of black and white squares that can be scanned by smartphones. Unlike static QR codes with fixed information, dynamic QR codes can generate unique transaction IDs and amounts for each payment, making them ideal for retail and online payments.
UPI dynamic QR codes can encode transaction details, merchant IDs, and payment amounts, enabling faster checkout and reducing errors. Each scan creates a fresh transaction request, ensuring better security and easy tracking.
