ABSTRACT:
A bar code reader is provided with the capability of reading bar code symbols containing information for causing changes in the functions performed by said reader, as well as reading merchandise identification symbols commonly associated with items such as merchandise being checked out at a point of sale terminal. Tests are provided to determine that the bar code symbols for function changes are proper symbols, and are not merchandise identification symbols, such as UPC symbols.
