US Patent 11409979 Method of barcode templating for enhanced decoding performance

An exemplary method of decoding a barcode uses a barcode template of known fixed fields in the barcode to enhance error correction in decoding of the barcode. A barcode having encoded data is scanned with an exemplary electronic device including a barcode scanner, a memory, and a barcode template stored in the memory. The barcode template includes fixed data fields and variable data fields. The barcode's encoded data are sampled into a codeword array, and a barcode template that matches the format of the scanned barcode is selected. Typically, error correction is then performed on the codeword array, and the error-corrected codeword array is then outputted.
