Method and system for pseudo bar code generation

A method for processing bar codes at point-of-sale (POS) terminals, the method comprising:

• determining by a bar code reader or scanner a bar code contained in an item;
• generating a pseudo bar code based on a received trigger signal by a pseudo bar code generator coupled to the bar code reader or scanner, wherein a point-of-sale terminal coupled to the pseudo bar code generator;
• if the trigger signal is not received by the pseudo bar code generator, sending by the pseudo bar code generator to the point-of-sale terminal a bar code determined by the bar code reader or scanner;
• if the trigger signal is received by the pseudo bar code generator, generating by the pseudo bar code generator, based on the trigger signal, a pseudo bar code, and sending by the pseudo bar code generator to the point-of-sale terminal the generated pseudo bar code;
• and
• generating by the point-of-sale terminal a sales slip, based on bar codes determined by the bar code reader or scanner, and pseudo bar codes generated by the pseudo bar code generator.

A computer program product for processing bar codes at point-of-sale (POS) terminals and including one or more computer readable instructions embedded on a computer readable medium and configured to cause one or more computer processors to perform the steps of:

• determining by a bar code reader or scanner a bar code contained in an item;
• generating a pseudo bar code based on a received trigger signal by a pseudo bar code generator coupled to the bar code reader or scanner, wherein a point-of-sale terminal coupled to the pseudo bar code generator;
• if the trigger signal is not received by the pseudo bar code generator, sending by the pseudo bar code generator to the point-of-sale terminal a bar code determined by the bar code reader or scanner;
• if the trigger signal is received by the pseudo bar code generator, generating by the pseudo bar code generator, based on the trigger signal, a pseudo bar code, and sending by the pseudo bar code generator to the point-of-sale terminal the generated pseudo bar code;
• and
• generating by the point-of-sale terminal a sales slip, based on bar codes determined by the bar code reader or scanner, and pseudo bar codes generated by the pseudo bar code generator.
