Abstract

The present disclosure relates to an electronic shelf label comprising a control unit and at least one memory unit holding information about a product associated with said label, said label comprising a receiver to receive from a handheld device a request for information about the product associated with the electronic shelf label, said control unit being arranged to process said request and select information stored in said at least one memory unit, and a transmitter to transmit said information to the handheld device in response to such request. The present disclosure also relates to a handheld device and a method for use in an electronic shelf label system.

Claims

1. An electronic shelf label being associated with a product comprising:

a control unit;

at least one memory unit operably connected to the control unit and to store information about a product associated with said label;

a receiver to receive from a hand-held device a request for information about the product associated with the electronic shelf label;

wherein said controller is to process said request and select information stored in said at least one memory unit; and

a transmitter to transmit said information to the handheld device in response to the request.

2. The electronic shelf label according to claim 1, wherein the transmitter is to wirelessly transmit said information to the handheld device.

3. The electronic shelf label according to claim 2, wherein transmitter of said information includes infrared (IR) communication means.

4. The electronic shelf label according to claim 3, wherein the control unit, memory unit, receiver and transmitter are in a radio frequency identification tag.

5. The electronic shelf label according to claim 1, wherein transmitter is an infrared (IR) transmitter.

6. The electronic shelf label according to claim 1, wherein transmitter of said information includes infrared (IR) communication means.

7. A handheld device for use in an electronic shelf label system comprising:

a transceiver to communicate with at least one electronic shelf label, wherein the transceiver includes;

a transmitter to request information about a product associated with the electronic shelf label, wherein the information includes price information,

a receiver to receive said information from the electronic shelf label; and

a memory to store said information.

8. The handheld device according to claim 7, further comprising calculator to add at least part of said information related to a price of the product to a total sum to be stored in the memory.

9. The handheld device according to claim 8, wherein the transmitter is to transmit a new authorization code matching an authorization code in a label to replace an old authorization code.

10. A method for use in an electronic shelf label system comprising:

transmitting from a handheld device to an electronic shelf label a request for information related to the product associated with said label;

receiving said request in the label;

processing said request in the label to verify that the requested information should be provided to the handheld device;

processing said request in the label to determine pieces of information that should be transmitted to the handheld device; and

transmitting the requested information to the handheld device.

11. The method according to claim 10, wherein the information related to said product preferably includes at least one of price information and a description of the product.

12. The method according to claim 10, wherein transmitting from a handheld device to an electronic shelf label a request includes storing the information or part of the information received from the label in a memory in the handheld device.

13. The method according to claim 10, wherein transmitting from a handheld device to an electronic shelf label a request includes adding price data in the requested information to previously received price data to provide a total sum indicating price information for several products associated with several independent labels.

14. The method according to claim 10, wherein transmitting from a handheld device to an electronic shelf label a request includes displaying at least part of the requested information on a display of the handheld device.

15. The method according to claim 10, wherein the information related to said product preferably includes at least one of price information and a description of the product and wherein transmitting from a handheld device to an electronic shelf label a request includes:

storing the information or part of the information received from the label in a memory in the handheld device;
