Electrum Payments connects businesses together to transact with each other easily and robustly. This Electrum QR Payment Retailer Interface documents the messaging interface used by Electrum to connect retailers and merchants together for performing QR code based payments.

This interface provides for the retailer side. The lifecycle of a QR code based payment can be encapsulated into three major phases - namely: the scan of the QR code by the customer, the request for tender by the retailer and the authorisation of this payment by the partner.
