Abstract

Methods of operation of a data reader and security tag deactivation system whereby a data reader such as a barcode scanner is equipped with EAS deactivation coils or modules disposed in the vicinity of the read volume or generally proximate thereto and the system is operable to permit reading of the ID tag (such as the barcode label) on an item, and upon a successful read, the deactivation unit is operable to (1) sense the presence of an EAS tag; (2) if presence of an EAS tag is sensed, energize the deactivation coil/module to deactivate the EAS tag; and (3) sense if the EAS tag is deactivated. If the EAS tag is sensed to have been deactivated, the system signals as such and a next item may be scanned. If the EAS tag is sensed to have not been deactivated, the system proceeds to alternate operational steps to handle the exception. In another function, the system is operable to urge the operator to return the item to the read volume to enhance EAS tag deactivation, one method being by delaying a good read acknowledgment until the system determines that the EAS tag which may have been previously detected has subsequently been deactivated.

Claims

1. A combined security tag unit and data reader system comprising:

a security tag deactivation unit arranged for deactivating an electronic security tag located proximate to the read volume of the data reader; and

a data reader for reading an ID tag,

wherein the data reader is operative to undergo a change in operation in response to input from the security tag deactivation unit.

2. A system according to claim 1 wherein the change in operation of the data reader comprises a delay in the data reader indicating a successful read of an ID tag in response to input from the security tag deactivation unit that an electronic security tag has been re-sensed after an attempt to deactivate.

3. A system according to claim 1 wherein the data reader is operative for arming the security tag deactivation unit upon a successful read of the ID tag.

4. A system according to claim 1 wherein the security tag deactivation unit comprises an EAS controller and an EAS deactivation device.

5. A system according to claim 1 wherein the data reader in configured to indicate a successful read of the ID tag only after both successful read of the ID tag and successful deactivation of the security tag have occurred, thereby avoiding multiple indications of the read of the same ID tag.

6. A system according to claim 1 wherein the ID tag and the electronic security tag are both contained within a single tag.

7. A system according to claim 6 wherein the single tag comprises a multiple function RFID tag.

8. A method of operating a system for reading ID tags and deactivating electronic security tags, comprised of a security tag deactivation unit and a data reader, the method comprising the steps of:

sensing to detect presence of an electronic security tag on an item proximate to a read volume of the data reader;

reading data from an ID tag on the item;

if an electronic security tag has been detected, attempting to deactivate the electronic security tag;

adjusting operation of the data reader in response to input from the security tag deactivation unit.

9. A method according to claim 8 further comprising

after attempting to deactivate, attempting to re-sense the a security tag.

10. A method according to claim 9 wherein the step of adjusting operation of the data reader in response to input from the security tag deactivation unit comprises

if the security tag is re-sensed, (1) providing a visual or audio cue to an operator to return the item to the read volume and (2) re-attempting to deactivate the electronic security tag.

11. A method according to claim 10 further comprising

notifying the operator of a failure to deactivate if repeated re-attempting to deactivate the electronic security tag.

12. A method according to claim 8 wherein the step of sensing to detect presence of an electronic security tag occurs at any one or more of the following times:

at the same time as the step of reading data from an ID tag, and

prior to the step of reading data from an ID tag.

13. A system according to claim 8 wherein the data reader is operative for arming the EAS controller upon a successful read of the ID tag.

14. A method of operating and controlling a system having a data reader defining a read volume and an associated security tag deactivation unit, for reading an ID tag and deactivating an electronic security tag on an item, the method comprising the steps of:

reading data from an ID tag located within the read volume of the data reader;

sensing for an electronic security tag;

if an electronic security tag is sensed, the security tag deactivation unit attempting to deactivate the electronic security tag,

wherein operation of the data reader is adjusted based on input from the security tag deactivation unit.

15. A method according to claim 14 wherein the security tag deactivation unit attempts to deactivate only if an ID tag is read within a predetermined time window proximate to the electronic security tag being sensed.

16. A method according to claim 14 further comprising

after attempting to deactivate, attempting to re-sense the a electronic security tag.

17. A method according to claim 16 further comprising

if the security tag is re-sensed, (1) providing a visual or audio cue to an operator to return the item to the read volume and (2) re-attempting to deactivate the electronic security tag.

18. A method according to claim 14 wherein operation of the data reader is adjusted by delaying acknowledgment of the data read from the data reader.

19. A method according to claim 14 further comprising attempting to deactivate a security tag only after data from an ID tag has been successfully read.

20. A method of operating a Point of Sale (POS) system having a data reader defining a read volume and an associated security tag deactivation unit, the method comprising the steps of:

the data reader reading data from an ID tag on an item located within the read volume;

the security tag deactivation unit sensing for an electronic security tag;

notifying the POS system of sensing results from the security tag deactivation unit.

21. A method according to claim 20 further comprising

the POS delaying transmitting back to the data reader confirmation of a good read depending upon sensing results received from the security tag deactivation unit.

22. A method according to claim 20 further comprising

the POS logging deactivation results received from the security tag deactivation unit.
