https://devzone.nordicsemi.com/f/nordic-q-a/41566/multiple-nfc-antennae-with-nrf52Hello, we are evaluating the nRF52 as SoC for a customer project that requires multiple NFC antennae (likely 3) to be able to quasi-simultaneously read 3 NFC tags in 3 physically different locations. Can that be directly achieved with an nRF52?

I was just worried that a mux might interfere with antenna performance.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/161701?ContentTypeID=1Thu, 13 Dec 2018 14:07:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1dcfcf0b-b521-43a3-b4c2-3c3f5a767472Andreas<p>Hi,</p> <p>&nbsp;</p> <p>This should not be a a problem, but it is nothing that we have support for in our current NFC implementation or any examples of. You will have to add the mux functionality yourself in your application.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
