Exit-code-based RFID loss-prevention system
Methods and systems are described for authorizing an item with an RFID tag to leave a facility. In one embodiment, a mobile device receives or determines an exit code (EC) to write into the tag in response to providing authorizing information. The EC may be based on information stored in the tag such as the tag's item identifier or other tag information (collectively an item identifier or II), a ticket value, other information such as the OC, a mobile identity or location, or any other suitable information. Upon verification of the EC, the tagged item is allowed to leave the facility. In another embodiment, the mobile device stores an item identifier (II) associated with the tag and provides authorizing information. Upon verifying the authorizing information and confirming that the stored II corresponds to the tagged item's II, the tagged item is allowed to leave the facility.
1. A component for a radio-frequency identification (RFID) self-checkout system to authorize items to leave a facility, the component comprising:
a reader interface configured to couple to an RFID reader;
a network interface configured to couple to a network; and
a processor configured to:
receive, via the reader interface, an item identifier (II) from an RFID tag associated with an item;
receive, via the network interface, an exit code (EC) based on information from a mobile device;
authorize, based on at least the EC and the II, the item to leave the facility.
2. The component of claim 1 , wherein:
the information is authorizing information, and
the processor authorizes the item to leave the facility by at least confirming that the authorizing information is valid.
3. The component of claim 2 , wherein the authorizing information includes at least one of customer identification information, payment information, and account information.
4. The component of claim 1 , wherein the mobile device is a mobile phone, a smart phone, a portable RFID reader, a laptop, or a tablet.
5. The component of claim 1 , wherein the processor is further configured to activate an alarm in response to:
determining that another item is leaving the facility; and
failing to receive a valid EC associated with the other item.
6. The component of claim 1 , wherein the processor is further configured to:
verify the item is associated with the facility prior to authorizing the item to leave the facility; and
permit another item not associated with the facility to leave the facility without authorization.
7. The component of claim 1 , wherein the component is separate from the RFID reader.
8. A component for a radio-frequency identification (RFID) self-checkout system, the component comprising:
a network interface; and
a processor configured to:
receive, via the network interface, an item identifier (II) from an RFID tag associated with an item located in a facility;
receive, via the network interface, an exit code (EC) based on information from a mobile device;
determine, based on the EC and the II, that the item is authorized to leave the facility; and
in response to the determination, send, via the network interface, an authorization for the item to leave the facility.
9. The component of claim 8 , wherein:
the information is authorizing information, and
the processor determines that the item is authorized to leave the facility by at least confirming that the authorizing information is valid.
10. The component of claim 9 , wherein the authorizing information includes at least one of customer identification information, payment information, and account information.
11. The component of claim 8 , wherein the mobile device is a mobile phone, a smart phone, a portable RFID reader, a laptop, or a tablet.
12. The component of claim 8 , wherein the processor is further configured to trigger an alert in response to:
determining that another item is leaving the facility; and
failing to receive a valid EC associated with the other item.
13. The component of claim 8 , wherein the processor is further configured to:
verify the item is associated with the facility prior to authorizing the item to leave the facility; and
permit another item not associated with the facility to leave the facility without authorization.
14. The component of claim 8 , wherein the component is remote from the facility.
15. A component for a radio-frequency identification (RFID) self-checkout system, the component comprising:
a network interface; and
a processor configured to:
receive, via the network interface, an identifier from an RFID tag associated with an item in a facility;
receive and attempt to verify authorizing information for the item; and
upon verifying the authorizing information, authorize the item to leave the facility.
16. The component of claim 15 , wherein the authorizing information is provided from a mobile device.
17. The component of claim 15 , wherein the authorizing information includes at least one of customer identification information, payment information, and account information.
18. The component of claim 15 , wherein, upon failing to verify the authorizing information, the processor is further configured to trigger an alert if the item leaves the facility.
19. The component of claim 15 , wherein the processor is further configured to:
verify the item is associated with the facility prior to authorizing the item to leave the facility; and
permit another item not associated with the facility to leave the facility without authorization.
20. The component of claim 15 , wherein the component is remote from the facility.
