Abstract

A label includes a first portion that is printable with optically readable information and a detachable second portion that has an RFID tag that can be encoded with corresponding RFID information. The printable portion and the RFID portion can thus be printed and encoded, respectively, with information for the same container or object. Both portions can then be kept together until the label is ready to be applied. This greatly reduces the chances of applying mismatched optical and RFID labels.

Claims

1. A label, comprising:

a first portion having an RFID tag and an adhesive layer disposed along a bottom surface thereof;

a second portion having a top surface imprintable with optically readable information and the adhesive layer disposed along a bottom surface thereof, wherein the second portion is separable from the first portion; and

a material disposed in the second portion, wherein the material changes at least one operational parameter of the RFID tag when the first portion is separated from the second portion.

2. The label of claim 1, wherein the first and second portions are separable along the width of the label.

3. The label of claim 1, wherein the first and second portions are separable along the length of the label.

4. The label of claim 1, further comprising separation means disposed between the first and second portions.

5. The label of claim 4, wherein the separation means comprises a perforation.

6. The label of claim 4, wherein the separation means are directly adjacent the first and second portions.

7. The label of claim 1. further comprising a third portion adjacent to and separable from the first portion, wherein the adhesive layer is bonded to an edge of the third portion.

8. The label of claim 7, wherein the first portion is disposed between the second and third portions.

9. The label of claim 1, wherein the material is selected from a group consisting of a conductor, a dielectric, and a magnetically permeable material.

10. The label of claim 1, wherein the material extends into the first portion.

11. The label of claim 1, wherein the material is in electrical contact with the RFID tag.

12. A method of using a label having an RFID tag portion, a printable portion for optically readable information, and an adhesive layer underlying the RFID tag and printable portions, the method comprising:

interrogating the RFID tag portion;

printing optically readable information on the printable portion;

separating the RFID tag portion from the printable portion; and

adhering the RFID tag portion and the printable portion to an object,

wherein the separating changes an operational parameter of the RFID) tag, wherein the operational parameter is selected from a group consisting of an operating frequency and a read range of the RFID tag portion.

13. The method of claim 12, wherein the interrogating comprises encoding the RFID tag portion.

14. The method of claim 12, wherein information in the RFID tag portion corresponds to the optically readable information on the printable portion.

15. The method of claim 12, wherein the printing is effected after the interrogating.

16. The method of claim 12, wherein the interrogating is effected at approximately the same time as the printing.

17. The method of claim 16, wherein the interrogating and the printing are effected side by side.

18. The method of claim 12, further comprising separating the RFID tag portion from an extension portion prior to the applying, wherein the adhesive layer below the RFID tag portion is bonded to the extension portion.

19. The method of claim 12, wherein the interrogating and printing are performed at a first location and the separating, removing, and applying are performed at a second location.
