Abstract

An RFID encoder is used in conjunction with a barcode print and apply system. The RFID encoder utilizes information obtained from a data stream from a host computer, from a corresponding barcode label, or other source to program an RFID label. The programmed label can then be applied with an integrated applicator or an external applicator. The RFID encoder can also verify that an RFID tag or label has been properly encoded and has the same content as the corresponding barcode label. The RFID can further verify that the barcode has been properly printed. If both barcode and RFID tag contain the correct data, both types of labels are attached to a package, enabling the package to be read optically and with radio frequency signals.

Claims

1. An RFID labeling system, comprising:

an RFID encoder receiving a signal and programming an RFID label based on the signal, wherein the signal contains information for programming the RFID label;

an RFID label applicator applying the programmed RFID label onto an object;

a host computer 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, wherein the RFID encoder extracts information from data streams of different programming languages.

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

3. The system of claim 2, wherein the optically readable label is a barcode label.

4. 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.

5. The system of claim 1, further comprising an optical label reader receiving the data steam for verifying that the optically readable label has been properly printed.

6. The system of claim 5, wherein properly printed comprises the optically readable label being readable and printed with the information corresponding to the data stream.

7. The system of claim 5, wherein the optical label reader is coupled to the RFID encoder for receiving the data stream.

8. The system of claim 1, wherein the optically readable label is a barcode label.

9. The system of claim 1, wherein the object is a container.

10. The system of claim 1, further comprising an optically readable label printer and applicator coupled to the host computer and receiving the data stream.

11. The system of claim 10, further comprising a conveyer system for moving the package past the optically readable label printer and applicator and the RFID encoder.

12. The system of claim 10, 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.

13. A method for applying an RFID label onto a package containing an optically readable label, the method comprising:

receiving a signal comprising RFID programming information from a host computer, wherein the signal is a data stream in a programming language;

programming the RFID label using the RFID programming information;

determining whether the optically readable label has been properly printed;

determining whether the RFID label has been properly programmed; and

applying the RFID label to the object if the optically readable label has been properly printed and the RFID label has been properly programmed, wherein the information for determining whether the RFID label has been properly programmed is extracted from data streams of different programming languages.

14. The method of claim 13, wherein the signal is read from a corresponding optically readable label.

15. The method of claim 14, wherein the optically readable label is a barcode label.

16. The method of claim 13, further comprising programming the RFID label using commands from the data stream.

17. The method of claim 13, wherein commands in the data stream are also used to print the optically readable label.

18. The method of claim 13, wherein determining whether the RED label has been properly programmed comprises comparing data on the optically readable label with data encoded in the RFID label.

19. The method of claim 13, wherein determining whether the optically readable label has been properly printed comprises determining whether the optically readable label is readable.

20. The method of claim 13, wherein determining whether the optically readable label has been properly printed comprises determining whether the optically readable label contains information from the data stream.

21. The method of claim 13, wherein determining whether the optically readable label has been properly printed comprises scanning the optically readable label.

22. A method of applying labels to packages in a system having an RFID encoder, the method comprising:

printing an optically readable label based on information contained in a data stream from a host computer, wherein the data stream is of different programming languages and wherein the RFID encoder extracts information from data streams of different programming languages;

applying the optically readable label onto a package;

verifying whether an RFID label has been properly programmed based on information contained in the data stream or in the optically readable label; and

applying the RFID label to a package if the RFID label has been properly programmed.

23. The method of claim 22, further comprising determining whether the optically readable label was printed properly.

24. The method of claim 23, wherein the determining comprises scanning the optically readable label.

25. The method of claim 23, wherein the determining comprises using information contained in the data stream.

26. The method of claim 22, further comprising writing to the RFID label using information from the data stream or the optically readable label before the verifying.

27. The method of claim 22, further comprising comparing the content of the optically readable label with the content of the RFID label.
