Wearable RFID device for use in an event-based interrogation zone

1. A server for enabling the processing of a transaction within an event interrogation zone, the server having a processor, a communication subsystem and a memory, each in communication with the processor, the memory storing instructions which when executed by the processor configure the server to:

maintain a database of RFID tags issued to users, the tags being embodied in a form factor that is worn or hand-held, each tag being associated with a UniqueID, the UniqueID being associated with an account having stored data including a stored funds balance;

make available a programmed functionality to a hand-held computing device capable of reading an RFID signal at 13.56 MHz frequency, the program including steps to:

activate the computing device upon presentation of the tag to the computing device in a first tap, read the tag's UniqueID, and communicate the UniqueID to a server for validation;

having received a validation message confirming the UniqueID, receive particulars of a transaction through the computing device;

receive a presentation of the tag in a second tap at the same computing device to confirm the particulars of the transaction;

process the transaction after validation that the same UniqueID was present in the first tap and the second tap, and cause the stored funds balance to be altered; and

inactivate the computing device to a state unable to receive further particulars for the same transaction after the tag is removed; and

update the account with respect to the altered stored funds balance once the transaction is completed.

2. The server of claim 1 , wherein the RFID tag communicates according to ICODE SLI2 16693 or 15693 standards.

3. The server of claim 1 wherein the transaction is a sales transaction for a good or service.

4. The server of claim 1 , wherein the transaction is an admission to an event within the interrogation zone.

5. The server of claim 1 , wherein the transaction is an admission to a restricted access area of the interrogation zone.

6. The server of claim 1 , wherein the transaction is a top-up transaction to add funds to the stored funds balance.

7. The server 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.

8. The server of claim 1 , wherein the UniqueID of the tag automatically expires or is deactivated after a predetermined time, or following the event.

9. The server of claim 1 , wherein the stored data further comprises at least one credential.

10. The server of claim 9 , wherein the credential is an age or date of birth credential.

11. The server of claim 9 , wherein the credential is an access or privilege credential.

12. The server of claim 9 , wherein the credential is communicated to the computing device at either the first tap or the second tap.

13. The server of claim 10 , wherein the transaction occurs in an age-restricted area.

14. The server of claim 10 , wherein the transaction is a sales transaction for an age-restricted product or service.

15. The server of claim 1 , wherein the stored data includes a link to a profile of the user.

16. The server of claim 1 , wherein the computing device is a phone.

17. The server of claim 1 , wherein the tag is in a phone.

18. The server of claim 1 , wherein receiving particulars includes scanning items to be purchased.

19. The server of claim 1 , wherein receiving particulars includes receiving a selection of goods or services from a GUI on the computing device.

20. The server of claim 1 , wherein the stored data and the stored funds balance are on the tag.

21. The server of claim 1 , wherein the stored data and the stored funds balance are on the computing device.
