Abstract
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.
Claims
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 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.
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 Mylar.

DETAILED DESCRIPTION
[0026] The production of a button according to an embodiment of the invention is illustrated in the figures.
[0027] As an initial matter, the button is an improvement of the prior art type shown in
[0028] The improvement involves a chip 22, a blocker layer 24, an annular receiver 26 and an overlay 28.
[0029] The chip 22 is an NFC tag, as shown in
[0030] The blocker layer 24 is disposed upon the back of the tag 22, as shown in
TABLE-US-00001 Name GAE Type Polymeric Suitable Frequency HF 13.56 MHz u1 MHz 15typ Standard Size (mm) 300*200 300*20000 Thickness (mm) 0.3 Merit Economical Halogen Free OK Working Temp 30 C. to +85 C.
[0031] For use: [0032] receiver 26 is disposed upon the prior art metal backer and the chip/blocker is disposed interiorly of the receiver, as shown in
[0037] Surprisingly, the NFC in button 20 is capable of activation in a conventional manner, i.e. by tapping a phone against it, notwithstanding the metal backer [that would be expected to interfere with operation].
[0038] Whereas a specific embodiment is shown, variations are possible.
[0039] For example, whereas a NFC tag is shown, an RFID chip could also be used. Further, whereas a printed insert is shown, printing is not strictly necessary. Whereas Mylar is indicated for the transparent layer, other materials could be used, and the printed and transparent layers could be combined. Additionally, other blockers could be used. Wave blockers of differing thickness can also be used; a range of 0.3 to 0.6 mm is known to be useful.
[0040] Accordingly, the invention should be understood to be limited only by the accompanying claims, purposively construed.
