US Patent 7934647 In-cart grocery tabulation system and associated method

An in-cart grocery tabulation system includes a shopping cart adapted to receive grocery items. A first and second scanner may be statically attached to a top region and a bottom region of the shopping cart respectively. Each of the first and second scanners may generate and transmit a price signal to a tabulation mechanism communicatively coupled to the first and second scanners. The tabulation mechanism may further be adapted to keep track of a price list associated with the scanned grocery items in the shopping cart. A display screen may be coupled to the tabulation mechanism and further affixed to the shopping cart to verify the price signal and thereafter transmits a display signal to the display screen. A user interface may be communicatively coupled to the display screen for reviewing the price list.
