Developed in 1974, Code 39 (aka Code 3 of 9, Code 3/9, Alpha39, Type 39, USS Code 39, or USD-3) is the first barcode symbology that could encode both numbers and alphabetical characters. It is used widely in non-retail environments.
pqScan .NET Barcode Scanner Control will save you a lot of effort if you are going to build a .NET application with Code 39 barcode scanning functionality. You don't need spend more time in looking into the complicated Code 39 encoding method, its checksum calculation, or any how wide or narrow bar and space differs from each other. The data information encoded in Code 39 linear bar code could be decoded and returned to your .NET application accurately. pqScan guarantees the decoding is totally compatible with Code 39 symbology standards ISO/IEC 16388:2007.
