NFC enabled button
View Patent ↗The improved button is of the type having: a metal backer, the backer carrying one of a safety pin and a magnetic clasp; and an overlay disposed upon and in gripping relation to the backer. The improvement includes: a chip disposed between the overlay and the backer, the chip being selected from the group consisting of Near Field Communication tag and RFID chip; and a layer of blocker disposed between the chip and the backer, the layer being adapted to permit operation of the chip.
1. An improved button of the type having
a metal backer, the backer carrying one of a safety pin and a magnetic clasp,
an overlay disposed upon and in gripping relation to the backer,
the improvement comprising:
a chip disposed between the overlay and the backer, the chip being a Near Field Communication tag; and
a solid blocker layer disposed between the chip and the backer, the layer disrupting or absorbing 13.56 mHz electromagnetic waves and thereby permitting activation of the chip by a Near Field Communication device placed against the overlay, the chip being positioned in proximity to the backer such that removal of the blocker layer would render the chip unsusceptible to activation by the device placed against the overlay.
2. The button of claim 1 , wherein the overlay comprises an opaque layer disposed proximal to the backer and a transparent layer disposed distal to the back and securing the opaque layer to the backer.
3. The button of claim 2 , wherein the opaque layer is a printed layer.
4. The button of claim 2 , wherein the transparent layer is biaxially-oriented polyethylene terephthalate.
5. An improved button of the type having
a metal backer, the backer carrying one of a safety pin and a magnetic clasp,
an overlay disposed upon and in gripping relation to the backer,
the improvement comprising:
an RFID chip disposed between the overlay and the backer; and
a solid blocker layer disposed between the RFID chip and the backer, the layer disrupting or absorbing 13.56 mHz electromagnetic waves and thereby permitting activation of the chip by an RFID device placed against the overlay, the chip being positioned in proximity to the backer such that removal of the blocker layer would render the chip unsusceptible to activation by the device placed against the overlay.
6. The button of claim 5 , wherein the overlay comprises an opaque layer disposed proximal to the backer and a transparent layer disposed distal to the back and securing the opaque layer to the backer.
7. The button of claim 6 , wherein the opaque layer is a printed layer.
8. The button of claim 6 , wherein the transparent layer is biaxially-oriented polyethylene terephthalate.
