https://devzone.nordicsemi.com/f/nordic-q-a/67242/nfc-project--blocker-tagHi everyone, Id like to know if anyone has tried to implement NFC Blocker Tag on NRF52480 or any similar nRF5 chip using their SDK. In general the purpose is to block a NFC ISO 14443-4 communication between a reader and a NFC tag that we want to protecten-USTelligent Community 13Fri, 16 Oct 2020 13:06:59 GMThttps://devzone.nordicsemi.com/thread/275373?ContentTypeID=1Fri, 16 Oct 2020 13:06:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e4763d7a-7fff-4d2f-99dc-d08f14aaa929Andreas<p>Hi,</p> <p>&nbsp;</p> <p>You might be able to do that with a fairly normal NFC implementation that might write just some arbitrary data to the reader, as the nRF52840 tag will degrade the mutual coupling between the reader antenna and the antenna in the rag that you want to protect. In other words acting as sort of a jammer. In any case your mileage may vary, you just have to try it out, as the nRF52840 tag implementation is not intended for such use.&nbsp;</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
