Abstract:
A method of decoding a machine readable barcode symbol comprising a number of characters including a number of error correction characters, each of the characters associated with a respective character code, the method comprising:reading the machine readable barcode symbol;selecting a group of successive characters from the machine readable barcode symbol, the number of characters in the selected group being equal to the number of error correction characters in the machine readable barcode symbol;attempting to solve an error correction equation using the character codes of the characters in the machine readable barcode symbol while identifying each of the characters in the selected group as erasures; andrepeating for successive groups of successive characters the selecting a group of successive characters and the attempting to solve an error correction equation using the character codes of the characters in the machine readable barcode symbol while identifying each of the characters in the selected group as erasures until either the error correction equation solves or each group of successive characters has been identified.
