A software tool that enables users to conduct basic validation of an EAN-13 barcode.
The module is also built to provide you with additional features, including the ability to return the correct check digit when given the 12 digit stem of a barcode. You can also leverage a method for identifying the country in which the manufacturer's identification code was registered, as well as a process for picking the most preferred barcode from a given list.
To use the Business::Barcode::EAN13 module, simply import the necessary functions using the qw/valid_barcode check_digit issuer_ccode best_barcode/ terms. From there, you can utilize these functions to verify the validity of specific barcodes, generate check digits, and identify the registered country codes.
For example, you can use the valid_barcode() function to evaluate whether or not a barcode is valid, like so: my $is_valid = valid_barcode("5023965006028");. Similarly, you can use the check_digit() function to generate the correct check digit for a 12-digit stem (in this case, "502396500602"): my $check_digit = check_digit("502396500602");.
Additionally, the issuer_ccode() function can be used to identify the registered country code for a given barcode: my $country_code = issuer_ccode("5023965006028");. Finally, you can use the best_barcode() function to identify the most preferred barcode from a given list, based on a provided set of country preferences: my $best_code = best_barcode(@barcodes, @prefs);.
Overall, if you need to validate EAN-13 barcodes and perform additional related tasks using Perl, Business::Barcode::EAN13 is a powerful and valuable module that can meet your needs with ease.
