First Claim
Patent Images
1. A bar code scanning apparatus for maintaining a personal inventory, comprising:
- a read-only memory module for storing a computer program and data;
a microprocessor coupled to said read-only memory module and able to execute said computer program;
a user input interface coupled to said microprocessor for receiving input and transmitting signals;
a bar code scanner coupled to said microprocessor for scanning bar codes and converting each bar code to the corresponding string of characters encoded within said bar code which are stored in a non-volatile memory module; and
a signal device whereby previously recorded bar codes in said non-volatile memory module are compared to newly scanned bar codes and said signal device is activated to transmit the results.
