Ring for use in near field communication (NFC) and method of making same
View Patent ↗A near field communication (NFC) ring and method of making a ring capable of NFC, the method including the steps of: providing an electrically conductive band with two ends separated by a through slit, fitting an NFC coil having an NFC antenna and NFC chip against a sleeve that is smaller in circumference than the NFC coil and is not electrically conductive; and attaching the sleeve to the inside of the band, thereby forming an NFC enabled ring.
1. A method of making a ring capable of near field communication (NFC), the method comprising the steps of:
a) providing an electrically conductive band for a ring, the band having two ends separated from one another by a through slit;
b) fitting an NFC coil comprising an NFC antenna and NFC chip against a continuous sleeve, wherein the sleeve is smaller in circumference than the NFC coil and is non-conductive; and
c) attaching the sleeve to the inside of the band so that the two ends remain separated from one another, thereby forming an NFC enabled ring.
2. The method of claim 1 , wherein the NFC coil's diameter is shortened to fit against an outer circumference of the sleeve by applying two folds to the NFC antenna that are on a same plane but in opposite directions.
3. The method of claim 1 , wherein the NFC coil is fitted against an indent along an outer circumference of the sleeve.
4. The method of claim 1 , wherein the NFC coil is covered with an epoxy resin or an adhesive that is not electrically conductive.
5. The method of claim 1 , wherein the sleeve is attached to the band by an adhesive and only the indent of the sleeve receives the adhesive.
6. The method of claim 1 , wherein the band is formed of a metal selected from a group consisting of gold or silver.
7. The method of claim 1 , wherein the through slit of the ring is filled with a non-conductive material.
8. A ring capable of near field communication, the ring comprising a non-conductive sleeve wrapped with an NFC coil comprising an NFC antenna and chip, the NFC coil covered by an electrically conductive ring band with two ends separated by a through slit, characterized in that the NFC antenna comprises two folds that are on a same plane but in opposite directions, thereby fitting the NFC coil directly against the sleeve.
