One of the best and popular barcode scanning library for Delphi is ZXing.Delphi library. ZXing Barcode Scanning Object Pascal library for Delphi VCL and Delphi Firemonkey.
ZXing.Delphi is a native Object Pascal library that is based on the well known open source Barcode Library: ZXing (Zebra Crossing). This port is based on the .Net Redth port of ZXing and the Java one. It is aimed at all of the FireMonkey mobile platforms and, starting from v3.1, it fully supports also Windows VCL applications (no dependencies on FMX.Graphics unit).
With this library, you can scan with native speed without the use of linking in external libraries and avoid compatibility issues and dependencies. It is fast.
