Reading a barcode

Adding barcode reading capabilities to your app can open several scenarios to your projects. It is a fast and convenient way to take some user input and return relevant information.

ML Kit can read most standard barcode formats, including linear and 2D formats: 

  • Linear: Code 39, Code 93, Code 128, Codabar, EAN-8, EAN-13, ITF, UPC-A, and UPC-E
  • 2D: Aztec, Data Matrix, PDF417, and QR code

In this recipe, you will see an easy way to add this feature to the sample app.
