This library is a port of the steplix/emv-qrcps library library which is a fork of Emmanuel Kiametis library to the .NET platform. Basically the implementation is the same, so the tutorial below has been copied and adapted for use in C#.

This library was made to help people that to generate and parse EMV QRcode according with the specifications:

Modules

There are 2 modules in this library.

  • Merchant - To work with QRCode according with the Merchant Specification.
  • Consumer - To work with QRCode according with the Consumer Specification.

Merchant Module

You can use this Module by importing:

using emv_qrcps.QrCode.Merchant;
