Wearable RFID device for use in an event-based interrogation zone
A wearable RFID device is provided for use in an event-based interrogation zone. The zone contains terminals with RFID readers. The device has an element worn by a user and an attached or embedded RFID tag. The tag has stored data representing a UniqueID of the tag, and a stored funds balance. The tag is programmed to activate an otherwise inactive one of said terminals upon presentation of the tag to the RFID reader of said terminal in a first tap, and communicate its UniqueID to the terminal for validation. Upon validation and following a second tap of the tag at the RFID reader, the tag's stored funds balance can be changed by the amount of a transaction run through said terminal. A temporary installation of a system of RFID-based terminals and user-worn RFID devices is also provided for use within an event interrogation zone.
1. A wearable RFID device for use in an event-based interrogation zone, the zone containing terminals with RFID readers, the device comprising:
an element worn by a user; and
an attached or embedded RFID tag having a memory having a first sector with a read-only memory storing a UniqueID of the tag, and a second sector with a read-write memory storing stored data including a stored funds balance;
the tag having a printed logic circuit, the circuit being programmed for activating an initially inactive one of said terminals upon presentation of the tag to the RFID reader of said terminal in a first tap, and communicating its UniqueID to the terminal for validation; and
the circuit being further programmed, upon validation, and following a second tap of the tag at the same RFID reader, for having the stored funds balance of the tag's read-write memory changed by the amount of a transaction run through said terminal between the first tap and the second tap, the terminal returning to inactive after the tag is removed.
2. The wearable RFID device of claim 1 , wherein the element is a wristband.
3. The wearable RFID device of claim 1 , wherein the element is a wearable event pass or badge.
4. The wearable RFID device of claim 1 , wherein the element is a disposable element.
5. The wearable RFID device of claim 1 , wherein the RFID tag is an ICODE SLI2 16693 tag or an ICODE SLI2 15693 tag.
6. The wearable RFID device of claim 1 , wherein the transaction is a sales transaction for a good or service.
7. The wearable RFID device of claim 1 , wherein the transaction is an admission to an event within the interrogation zone.
8. The wearable RFID device of claim 1 , wherein the transaction is an admission to a restricted access area of the interrogation zone.
9. The wearable RFID device of claim 1 , wherein the transaction is a top-up transaction to add funds to the stored funds balance.
10. The wearable RFID device of claim 1 , wherein the transaction is a cash-out transaction to cash out or transfer to another account or another device funds from the stored funds balance.
11. The wearable RFID device of claim 1 , wherein the tag is further programmed to deactivate or hibernate after a predetermined time, or following the event.
12. The wearable RFID device of claim 1 , wherein the stored data further comprises at least one credential.
13. The wearable RFID device of claim 12 , wherein the credential is an age or date of birth credential.
14. The wearable RFID device of claim 12 , wherein the credential is an access or privilege credential.
15. The wearable RFID device of claim 12 , wherein the credential is communicated to the terminal at either the first tap or the second tap.
16. The wearable RFID device of claim 13 , wherein the transaction occurs in an age-restricted area.
17. The wearable RFID device of claim 13 , wherein the transaction is a sales transaction for an age-restricted product or service.
18. The wearable RFID device of claim 13 , wherein the transaction is a sales transaction for an alcoholic beverage.
19. The wearable RFID device of claim 1 , wherein the adjusted stored funds balance is written to the read-write memory of the tag.
20. The wearable RFID device of claim 1 , wherein the stored data includes a link to transaction data stored offsite.
21. The wearable RFID device of claim 1 , wherein all stored data is stored directly in the read-write memory of the tag.
22. A temporary installation of a system of RFID-based terminals and user-worn RFID devices within an event interrogation zone, the installation comprising:
a plurality of terminals temporarily installed in the zone, each terminal having an active RFID reader, and being in communication with a server;
a plurality of RFID devices issued to users wishing to enter the zone, each RFID device comprising:
an element worn by a user; and
an attached or embedded RFID tag having a memory having a first sector with read-only memory storing a UniqueID of the tag, and a second sector with a read-write memory storing stored data including a stored funds balance;
the initially inactive terminals being programmed for:
activating upon presentation by a user of the RFID tag of one of the RFID devices to the RFID reader using a first tap, and retrieving the UniqueID of the RFID tag;
validating the RFID tag by comparing the retrieved UniqueID to a database of valid UniqueIDs stored on a server in communication with the terminal;
receiving input of transaction particulars through the terminal;
processing the transaction after the validated RFID tag is presented to the RFID reader of the terminal in a second tap, the processing including altering the stored funds balance on the read-write memory of the RFID tag; and
inactivating the terminal after the tag is removed.
23. The temporary installation of claim 22 , wherein the readers and tags use an Active Reader Passive Tag (ARPT) system.
24. The temporary installation of claim 22 , wherein the terminals are further programmed for disallowing input of transaction particulars while the terminal is inactive.
