Abstract

A portable data collection device adapted to be mounted to a shopping cart includes a housing having a clamping assembly for releasably clamping the housing to a pushing bar of a shopping cart. The housing defines an interior region supporting device electronics. The device further includes an interactive touch sensitive visual display screen and a retractable, tethered dataform reader releasably mounted on the housing. When mounted on the housing, an imaging assembly and an illumination assembly of the reader are continuously actuated to read a dataform presented to the reader. When removed from the housing, the reader is actuated by depressing a trigger on the reader. The device also includes a magnetic stripe reading assembly and communications circuitry including a radio transceiver module.

a coupon a recipe and a receipt, the electronic circuitry including;

i) a processor for controlling operations of the electronic circuitry and the dataform reader;

ii) decoding circuitry for decoding the dataform read by the dataform reader to generate decoded data related to the item;

iii) communications circuitry responsive to the decoding circuitry for transmitting a portion of the decoded dataform data to a remote device and receiving data relating to the item from the remote device;

iv) electronic memory for storing at least a portion of the decoded dataform data and at least a portion of the data received from the remote device;

d) a visual display screen supported by the housing for displaying in human recognizable form at least a portion of the decoded dataform data and at least a portion of the data retrieved from the remote device; and

e) input means supported by the housing for interfacing with the processor.

2. The portable data collection device of claim 1 wherein the housing includes a clamping mechanism for releasably affixing the device to a shopping cart.

3. The portable data collection device of claim 1 wherein the dataform reader is releasably coupled to the housing with a retractable electrical cable.

4. The portable data collection device of claim 1 wherein the visual display screen includes a touch sensitive panel which functions as the input means.

5. The portable data collection device of claim 1 wherein the electronic circuitry is electrically coupled to a power source spaced apart from the housing.

6. The portable data collection device of claim 1 wherein the retrieved data includes the price and product name of the item whose dataform was read and decoded.

7. The portable data collection device of claim 6 wherein the price and product name of the item is displayed on the visual display screen.

8. The portable data collection device of claim 7 wherein the device is employed to read and decode dataforms affixed to a plurality of items and, for each item, the price and product name of the item is retrieved from the remote device and displayed on the visual display screen and the processor additionally displays a total sum of the prices for all of the items whose dataforms were read and decoded.

9. The portable data collection device of claim 7 wherein the receipt includes a price and product name for each item whose dataform was read and decoded.

10. The portable data collection device of claim 4 wherein the visual display screen displays a screen layout including a virtual keyboard comprised of a plurality of alphabetic keys and wherein a user of the device sequentially touches a series of the alphabetic keys to input data or commands to the processor.
