The controller is automatically configured for detecting a symbol having a specific symbology, for decoding the symbol having the specific symbology, for processing the receipt acknowledgment only when the symbol having the specific symbology has been detected and decoded, and for decoding symbols having symbologies different from the specific symbology when the symbol having the specific symbology has not been detected. ## Claims ### Claim 1 An imaging reader for imaging symbols of different symbologies and a receipt acknowledgement, comprising: a solid-state imager having an array of image sensors for capturing return light from the symbols of different symbologies and the receipt acknowledgement over a field of view to form a captured image; a controller operatively connected to the imager, and automatically configured for detecting a symbol having a specific symbology for automatically switching in real time without operator interaction between at least two operation modes; and wherein the controller decodes said symbol having said specific symbology and processes the receipt acknowledgement captured in the image in a first mode of operation after the captured image is obtained only if said symbol in the captured image having said specific symbology has been detected and decoded, and wherein the controller further decodes symbols having symbologies different from said specific symbology and does not process the receipt acknowledgement captured in the image in a second mode of operation if said symbol having said specific symbology has not been detected. ### Claim 2 (depends on 1) The reader of claim 1, wherein the controller is configured for detecting whether said symbol has a predetermined number of data characters lying within a predetermined range of said data characters. ### Claim 3 (depends on 1) The reader of claim 1, wherein the controller is configured for processing the receipt acknowledgment in a receipt area of the field of view. ### Claim 4 (depends on 1) The reader of claim 1, wherein the controller is configured for locating a symbol area in the field of view of said symbol having said specific symbology, and for locating the receipt area based on the located symbol area. ### Claim 5 (depends on 1) The reader of claim 1, wherein the controller is configured for transmitting both the processed receipt acknowledgment and said decoded symbol having said specific symbology away from the controller, only after both said symbol having said specific symbology has been detected and decoded, and only after the receipt acknowledgment has been processed. ### Claim 6 An imaging reader for imaging symbols of different symbologies and a receipt acknowledgment, comprising: means for capturing return light from the symbols of different symbologies and the receipt acknowledgment over a field of view to form a captured image; control means for detecting a symbol in the captured image having a specific symbology, for decoding said symbol having said specific symbology, for 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, and for 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. ### Claim 7 (depends on 6) The reader of claim 6, wherein the control means is configured for detecting whether said symbol has a predetermined number of data characters lying within a predetermined range of said data characters. ### Claim 8 (depends on 6) The reader of claim 6, wherein the control means is configured for processing the receipt acknowledgment in a receipt area of the field of view. ### Claim 9 (depends on 8) The reader of claim 8, wherein the control means is configured for locating a symbol area in the field of view of said symbol having said specific symbology, and for locating the receipt area based on the located symbol area. ### Claim 10 (depends on 6) The reader of claim 6, wherein the control means is configured for transmitting both the processed receipt acknowledgment and said decoded symbol having said specific symbology away from the controller, only after both said symbol having said specific symbology has been detected and decoded, and only after the receipt acknowledgment has been processed. ### Claim 11 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. ### Claim 12 (depends on 11) The method of claim 11, and a step of detecting whether said symbol has a predetermined number of data characters lying within a predetermined range of said data characters. ### Claim 13 (depends on 11) The method of claim 11, wherein the step of processing the receipt acknowledgment is performed in a receipt area of the field of view. ### Claim 14 (depends on 13) The method of claim 13, and a step of locating a symbol area in the field of view of said symbol having said specific symbology, and a step of locating the receipt area based on the located symbol area. ### Claim 15 (depends on 11) The method of claim 11, a step of transmitting both the processed receipt acknowledgment and said decoded symbol having said specific symbology, only after both said symbol having said specific symbology has been detected and decoded, and only after the receipt acknowledgment has been processed.
