SL-NFC-40

Conventional NFC Tags don't work when applied to metal surfaces, by placing a NFC tag on a metal surface, the efficiency of data transmission is greatly suppressed due to the generation of eddy currents within the metal surface. The reason NFC Tags don't work on metal is that the metal surface behind the tag acts as a ground plane and reduces the performance of the tag's antenna, effectively stopping it creating the current needed to power the chip. To increase the efficiency and range while minimizing the losses due to eddy currents, a soft magnetic sheet can be inserted between the metal case and the antenna. On- metal (or Anti-metal) NFC Tags are specially manufactured with a layer made of Highly Permeable magnetic sheet, so that they can work also if sticked directly to a metal surface.
