Abstract

An RFID print system includes an RFID printer and reader, a host computer that transmits a data stream containing instructions or commands to the RFID printer for encoding an RFID tag, and a data manager that receives EPC data or other data from the encoded tag. The data manager transmits the data to the host computer, which can then compare what was encoded to what was intended to be encoded. The host computer can then transmit signals to other devices in the system for appropriate action, such as when the encoded tag is defective.

Claims

1. An RFID printer system, comprising:

an RFID encoder coupled to receive a signal and program an RFID label based on the signal, wherein the signal contains information for programming the RFID label; and

a computer coupled to the RFID encoder, wherein the host computer receives data programmed on the RFID label.

2. The system of claim 1, wherein the data is EPC (Electronic Product Code), GTIN (Global Trade Identification Number), or SSCC (Serialized Shipping Container Code) data.

3. The system of claim 1, further comprising a host computer adapted to receive data from the computer and transmit the signal to the RFID encoder.

4. The system of claim 1, wherein the computer is adapted to transmit the signal to the RFID encoder.

5. The system of claim 1, wherein the computer is a host computer capable of sending the signal to the RFID encoder, wherein the signal is a data stream having a first programming language and comprising instructions for printing an image on an optically readable label.

6. The system of claim 1, further comprising an optical label reader capable of sending the signal to the RFID encoder, wherein the signal comprises data read from an optically readable label.

7. The system of claim 1, wherein the RFID encoder verifies that information contained in an optically readable label matches data programmed on the RFID label.

8. The system of claim 5, wherein the RFID encoder is capable of extracting information from data streams of different programming languages.

9. The system of claim 5, further comprising an optical label reader adapted to receive the data stream for verifying that the optically readable label has been properly printed.

10. The system of claim 5, wherein the optically readable label is a barcode label.

11. The system of claim 9, wherein the optical label reader is coupled to the RFID encoder for receiving the data stream.

12. The system of claim 5, further comprising an optically readable label printer and applicator coupled to the host computer and adapted to receive the data stream.

13. The system of claim 12, further comprising a conveyer system for moving the package past the optically readable label printer and applicator and the RFID encoder.

14. The system of claim 12, wherein the optically readable label printer and applicator applies the optically readable label to the package prior to the object passing by the RFID encoder.

15. A method for processing an RFID label, comprising:

receiving, from a computer, a signal comprising RFID programming information;

programming the RFID label using the RFID programming information; and

transmitting data from the programmed RFID label to the computer.

16. The method of claim 15, wherein the data is EPC (Electronic Product Code), GTIN (Global Trade Identification Number), or SSCC (Serialized Shipping Container Code) data.

17. The method of claim 15, further comprising comparing, by the computer, the transmitted data and the RFID programming information.

18. The method of claim 15, wherein the transmitting comprises receiving the data, processing the data, and transmitting the processed data to the computer.

19. The method of claim 15, further comprising transmitting a second signal from the computer to a device for acting on the second signal.

20. The method of claim 19, wherein the second signal indicates whether the programming was correct.

21. The method of claim 19, wherein the acting comprises removing the RFID label before application onto a package if the second signal indicates the programming was faulty.

22. The method of claim 15, wherein the signal is a data stream in a programming language.

23. The method of claim 15, wherein the signal is read from a corresponding optically readable label.

24. The method of claim 15, wherein the signal is a data stream in a programming language, the method further comprising

determining whether an optically readable label has been properly printed on a package;

determining whether the RFID label has been properly programmed; and

applying the RFID label to the package if the optically readable label has been properly printed and the RFID label has been properly programmed.

25. The method of claim 24, further comprising programming the RFID label using commands from the data stream.

26. The method of claim 24, wherein commands in the data stream are also used to print the optically readable label.

27. The method of claim 24, wherein the information for determining whether the RFID label has been properly programmed is extracted from data streams of different programming languages.

28. The method of claim 24, wherein determining whether the RFID label has been properly programmed comprises comparing data on the optically readable label with data encoded in the RFID label.

29. The method of claim 24, wherein determining whether the optically readable label has been properly printed comprises determining whether the optically readable label is readable.

30. The method of claim 24, wherein determining whether the optically readable label has been properly printed comprises determining whether the optically readable label contains information from the data stream.

31. The method of claim 24, wherein determining whether the optically readable label has been properly printed comprises scanning the optically readable label.

32. A printer system, comprising:

an RFID printer, comprising;

an RFID antenna; and

an RFID reader;

a host computer configured to transmit a signal to the RFID printer, wherein the signal includes information for the RFID printer to encode data on an RFID tag; and

wherein the RFID printer is configured to transmit the encoded data back to the host computer.

33. The system of claim 32, further comprising a data manager configured to receive the encoded data from the RFID printer and to transmit data to the host computer.

34. The system of claim 32, wherein the data is an EPC, GTIN, or SSCC.
