Abstract

Systems and methods are provided for labeling a piece of merchandise with a wireless communication device. In addition to a wireless communication device, the merchandise tag includes an associated label made of a washable fabric material. The wireless communication device is incorporated into the label and includes an RFID chip and a slot-loop hybrid antenna, with the antenna including a conductor sheet that defines a slot. The label is secured to a piece of merchandise at a sew line, with the sew line dividing the label into an upper portion and a lower portion. The RFID chip and the slot of the antenna are positioned within the upper portion of the label, which may itself be positioned within a seam or neckline or waistband of the piece of merchandise.

Claims

1. A method for labeling a piece of merchandise, comprising:

providing a piece of merchandise;

providing a merchandise tag including a label formed of a fabric material and a wireless communication device incorporated into the label, the wireless communication device including an RFID chip and a slot-loop hybrid antenna electrically coupled to the RFID chip and including a conductor sheet defining a slot, the conductor sheet having an upper portion and a lower portion; and

securing the merchandise tag to the piece of merchandise at a sew line, which divides the label into an upper portion and a lower portion, wherein the merchandise tag is secured to the piece of merchandise such that

the upper portion of the label is smaller than the lower portion of the label, and

the slot is defined in one of the upper and lower portions of the conductor sheet and the one of the upper and lower portions of the conductor sheet having a greater durability.

2. The method of claim 1, wherein the piece of merchandise includes a seam or neckline or waistband and said securing the merchandise tag to the piece of merchandise includes securing the merchandise tag to the piece of merchandise such that the upper portion of the label is positioned within the seam or neckline or waistband.

3. The method of claim 1, wherein said securing the merchandise tag to the piece of merchandise includes securing the merchandise tag to the piece of merchandise such that the conductor sheet is at least partially positioned within the sew line.

4. The method of claim 1, wherein said securing the merchandise tag to the piece of merchandise includes securing the merchandise tag to the piece of merchandise such that the conductor sheet is at least partially positioned within the lower portion of the label.

5. The method of claim 1, wherein the conductor sheet has a width approximately equal to the width of the label and a height approximately equal to the height of the label.

6. The method of claim 1, wherein said providing a merchandise tag includes providing a merchandise tag formed of two pieces having different stiffness.

7. The method of claim 6, wherein the slot is defined in the piece of the conductor sheet having a greater stiffness than the other piece of the conductor sheet.

8. The method of claim 1, wherein the conductor sheet is rectangular.

9. The method of claim 1, wherein the conductor sheet is a conductive foil.

10. The method of claim 1, wherein the slot is substantially horizontal.

11. The method of claim 1, wherein the slot is vertical.

12. The method of claim 1, wherein the merchandise tag is formed of a single fabric layer.

13. The method of claim 1, wherein the merchandise tag is formed of a plurality of fabric layers.

14. The method of claim 1, wherein the chip is positioned entirely within an upper 10-20% of a height of the conductor sheet.

15. The method of claim 1, wherein the conductor sheet uses conductive threads which are woven into the label.
