Abstract
A reader generates a scanning beam for reading a bar code symbol on a selected item. The reader includes a database in which codes for all symbols to be read are stored, and frequency of use data indicative of how often each stored code has been read. A processor compares the code of the symbol being scanned with the stored codes. Upon a successful comparison, the code is processed as a valid code. Upon failure to match the code to one of the stored codes, a most likely code is selected as the valid code. The most likely code is based on the frequency of use data.
