Abstract

A device and method is provided for converting product-specific identification numbers associated with bar code indicia on pharmaceutical products to an industry standard identification number. The process involves reading a bar code indicia, converting the indicia into an input string and standardizing the input string by means of adding or subtracting characters in accordance with rules based on the bar code type and length of the input string. By means of the invention pharmaceutical products of two different sources may be compared to determine if they contain the same drug as determined by the standard identification number. The device can include a removable member for interchanging and updating bar code indicia information rather than reprogramming the device.
