https://community.nxp.com/t5/LPC-Microcontrollers/Writing-data-to-OM2NTP5332/m-p/1568425#M50998 <P>I am using the OM2NTP5332 NFC card with an Elatec TWN4 MultiTech 2 HF NFC reader/writer. I am trying to write some arbitrary data to the card (a type 5, ISO15693 64 bit card)</P><P>With a program called Director V4.50.1 I got with the reader from Elatec, I can read the ID and Tag Type from the NFC card as well as individual blocks of data from the card. However, I am unable to write any data to the card and I am unsure why.</P><P>It does work to write and read to the card using the NFC chip on my phone, which uses the ISO14443/MIFARE (32 bit) standard. Can you please advise me on what the problem might be and how I can resolve it? Could there some sort of security feature on the card that blocks the reader from writing to it but not my phone?</P> Mon, 12 Dec 2022 15:27:40 GMT srgzsdf32 2022-12-12T15:27:40Z https://community.nxp.com/t5/LPC-Microcontrollers/Writing-data-to-OM2NTP5332/m-p/1568425#M50998 <P>I am using the OM2NTP5332 NFC card with an Elatec TWN4 MultiTech 2 HF NFC reader/writer.
