Linking an electronic receipt to a consumer in a retail store

A theft deterrent system using a commerce server comprising a processing device having:

• a receiving module configured to receive a first video signal containing an image of a consumer's face at a checkout station and a second video signal of the consumer's face generated at an exit of a retail store;
• a linking module configured to link a receipt of a purchase by the consumer of at least one product with the image of the consumer's face;
• a video processing module configured to identify the consumer in the second video signal based on the image of the consumer's face in the first video signal;
• and
• a transmission module configured to transmit a receipt signal containing the receipt to a display positioned at the exit of the retail store.

A computer-implemented method comprising:

• transmitting, with a first camera, a first video signal containing an image of a consumer's face to a processing device of a commerce server from a checkout station in a retail store;
• receiving, at the processing device, a receipt signal containing a receipt of purchase by the consumer of at least one product from the checkout station;
• linking, with the processing device, the receipt with the image of the consumer's face;
• transmitting, to the processing device, a second video signal generated by a second camera positioned proximate to an exit of a retail store;
• identifying, with the processing device, the consumer in the second video signal based on the image of the consumer's face contained in the first video signal;
• and
• receiving at a display positioned proximate to the exit of the retail store, from the processing device, a receipt signal containing the receipt in response to the identifying step.
