Abstract

Embodiments of a radio frequency identification tag are generally described herein. Other embodiments may be described and claimed.

Claims

1. A radio frequency identification (RFID) tag comprising:

an antenna to send and receive data across a wireless interface;

an auxiliary interface device to couple with an apparatus external to the RFID tag; and

a memory device to store the data, the memory device including at least a first port associated with the antenna and a second port associated with the auxiliary interface device.

2. The RFID tag of claim 1, wherein the memory device comprises at least one of a non-volatile memory or a non-volatile random access memory.

3. The RFID tag of claim 1, wherein the auxiliary interface device includes a communication link to communicate data information to and from the memory device.

4. The RFID tag of claim 1, wherein the auxiliary interface device includes a power link to provide power to the RFID tag.

5. The RFID tag of claim 1, wherein the memory device to store data received from the auxiliary interface device when the RFID tag is in a passive mode.

6. The RFID tag of claim 1, wherein the apparatus external to the RFID tag to read the data from the memory device and across the auxiliary interface device when the RFID tag is in a passive mode.

7. The RFID tag of claim 1, further comprising a power conversion circuit to provide power to at least the memory device based on a signal received by the antenna across the wireless interface.

8. The RFID tag of claim 1, further comprising a transmit/receive circuit to control operations of the RFID tag.

9. A system comprising:

a radio frequency identification (RFID) device having a non-volatile memory device to communicate via both an air interface and a wired interface, the RFID device including a power source link to provide power to the RFID device and a communication link to send/receive communication data to/from the non-volatile memory device.

10. The system of claim 9, further comprising server components to couple with the RFID device across the wired interface.

11. The system of claim 10, wherein the server components to further couple with a wireless network.

12. The system of claim 10, wherein the non-volatile memory device to store the data received from the server components across the wired interface when the RFID device is in a passive mode.

13. The system of claim 10, wherein the server components to read data from the non-volatile memory device across the wired interface when the RFID device is in a passive mode.

14. The system of claim 9, wherein the RFID device includes an antenna to send and receive data across the wireless interface.

15. The system of claim 14, wherein the RFID device further includes a power conversion circuit to provide power to at least the non-volatile memory device based on a signal received by the antenna across the wireless interface.

16. A method comprising:

communicating second data between the RFID tag and another device via a second interface.

17. The method of claim 16, further comprising providing power to the RFID tag using the second interface.

18. The method of claim 16, wherein communicating the second data between the RFID tag and the another device includes:

providing the second data from the another device;

transmitting the second data from the another device across the second interface to the RFID tag; and

storing the second data within a non-volatile memory device of the RFID tag.

19. The method of claim 18, wherein storing the second data includes storing the second data within the non-volatile memory device when the RFID tag is in a passive mode.

20. The method of claim 16, wherein communication the second data between the RFID tag and the another device includes:

reading the second data from a non-volatile memory device of the RFID tag;

transmitting the second data across the second interface to the another device; and

receiving the second data at the another device from the second interface.

21. A system comprising:
