ngx-qrcode2 An Angular 6 Component library for Generating QR (Quick Response ) Codes.

You can use the ngx-qrcode2 to easily generate QR codes inside your Angular 6 or Ionic 3 applications

QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. A barcode is a machine-readable optical label that contains information about the item to which it is attached. A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to efficiently store data; extensions may also be used. Source
