Abstract

A system includes a host computing device, a first RFID transceiver, and at least one second RFID transceiver. The host computing device executes an application according to a predetermined RFID communication protocol. The predetermined RFID communication protocol supports communication only with a single RFID transceiver. The first RFID transceiver communicates with the host computing device according to the predetermined RFID communication protocol. The at least one second RFID transceiver communicates with the first RFID transceiver. The at least one second RFID transceiver provides data to the host computing device only via the first RFID transceiver.

Claims

1. A system, comprising:

a host computing device executing an application according to a predetermined RFID communication protocol, the predetermined RFID communication protocol supporting communication only with a single RFID transceiver;

a first RFID transceiver communicating with the host computing device according to the predetermined RFID communication protocol; and

at least one second RFID transceiver communicating with the first RFID transceiver,

wherein the at least one second RFID transceiver provides data to the host computing device only via the first RFID transceiver.

2. The system of claim 1, wherein the host computing device provides response data to the second RFID transceiver only via the first RFID transceiver.

3. The system of claim 1, wherein the data is one of an RFID tag identifier, a time stamp, a product identifier, a product serial number, a product manufacturing date and a product transaction data.

4. The system of claim 2, wherein the response data is one of a command and a parameter value.

5. The system of claim 2, wherein the response data corresponds to the data.

6. The system of claim 1, wherein the second RFID transceiver receives the data from an RFID transponder.

7. The system of claim 1, wherein the first RFID transceiver is one of fixed and handheld.

8. The system of claim 1, wherein the second RFID transceiver is one of a fixed RFID transceiver, a handheld RFID transceiver and an antenna array.

9. A method, comprising:

receiving, by a first RFID transceiver, data from at least one second RFID transceiver; and

sending, by the first RFID transceiver, the received data to a host computing device according to a predetermined RFID communication protocol, the predetermined RFID communication protocol supporting communication only with a single RFID transceiver,

wherein the at least one second RFID transceiver provides data to the host computing device only via the first RFID transceiver.

10. The method of claim 9, further comprising:

receiving, by the first RFID transceiver, response data from the host computing device; and

sending, by the first RFID transceiver, the response data to the at least one second RFID transceiver.

11. The method of claim 10, wherein the response data corresponds to the data.

12. The method of claim 9, wherein the at least one second RFID transceiver receives the data from an RFID transponder.

13. The method of claim 9, wherein the data is one of an RFID tag identifier, a time stamp, a product identifier, a product serial number, a product manufacturing date and a product transaction data.

14. The method of claim 10, wherein the response data is one of a parameter value and a command.

15. The method of claim 9, wherein the first RFID transceiver is one of fixed and handheld.

16. The method of claim 9, wherein the second RFID transceiver is one of a fixed RFID transceiver, a handheld RFID transceiver, and an antenna array.

17. A computer readable storage medium including a set of instructions executable by a processor, the instructions operable to:

receive data, by a first RFID transceiver, from at least one second RFID transceiver;

send the data, by the first RFID transceiver, to a host computing device according to a predetermined RFID communication protocol, the predetermined RFID communication protocol supporting communication only with a single RFID transceiver,

wherein the host computing device receives data from the at least one second RFID transceiver only via the first RFID transceiver.
