Static QR

Overview

A UPI QR code is a machine-scannable Quick Response (QR) code that contains the merchant's UPI details. To initiate a payment, a payer can scan the code using their UPI payment app (such as Gpay, PayTM, etc.). These codes must comply with NPCI’s UPI infrastructure requirements to ensure that the merchant's details are stored securely and that there are no errors during the payment journey.

Static QR codes usually only contain the merchant’s UPI VPA (virtual payment address). This makes them highly reusable; a merchant can accept multiple payments via static QR. Such QR codes can be easily printed and shared with the payer at the time of payment, requiring very little effort in terms of technical integration from the merchant. On the other hand, the payer will have to manually enter the transaction amount on their UPI payment app when scanning a static QR. UPI QR’s found in most retail stores or public vehicles are Static QR’s

Flow

Below is the flow of Decentro's static QR flow.

The platform reaches out to Decentro and shares the relevant merchant details who will collect the funds.
Decentro creates a UPI handle for the merchant, which the merchant can create a QR at their end OR
Decentro can create multiple QR codes for each merchant on the platform.
Decentro maps each QR code to a ledger account designed to hold the balance.
A payer scans the QR code from their app and pays using the UPI app of their choice.
Decentro triggers an Account Balanceto the end-point configured by the platform.
