Imaging reader for and method of receipt acknowledgment and symbol capture

A method of imaging symbols of different symbologies and a receipt acknowledgment, comprising the steps of:

• capturing return light from the symbols of different symbologies and the receipt acknowledgment over a field of view to form a captured image;
• detecting a symbol in the captured image having a specific symbology;
• decoding said symbol having said specific symbology;
• processing the receipt acknowledgment in the captured image only when said symbol in the captured image having said specific symbology has been detected and decoded;
• decoding symbols having symbologies different from said specific symbology without processing the receipt acknowledgment in the captured image when said symbol having said specific symbology has not been detected;
• and
• wherein the step of decoding said symbol in the captured image having said specific symbology and the step of processing the receipt acknowledgment in the captured image are performed in a first mode of operation, and wherein the step of decoding said different symbologies is performed in a second mode of operation;
• and a step of automatically switching in real time without operator interaction between the modes.
