The advent of check digit methods has aided the detection of errors while computing data into an information system. Prominent check digit methods such as Universal Product Code (UPC), International Standard Book Number (ISBN-10), Luhn and Verhoeff check digit methods are widely used in detecting errors. This research will focus on the current UPC method as it is used widely around the world. The current UPC Method does not effectively detect all types of errors. Thus, failure to detect errors can lead to undesired consequences like purchasing a wrong item or letting perpetrators to get away with their crimes. In this thesis, we examined the limitations of UPC check digit method and also proposed the idea of a double check digit method which produces two check digits. The proposed method is an enhancement of the current UPC modulus 10 check digit method. Tests were conducted to compare the error detection capability of the proposed method with three other check digit methods. Thus, results have shown that the proposed method has an error detection accuracy of 95.75%. While the UPC, ISBN and Luhn have error detection accuracy 65%, 86.75% and 56.75% respectively. Hence, the proposed method is more efficient in error detection as compared to the UPC, ISBN and Luhn check digit methods.
