Hello,

I would like to know if NT3H2111(NTAG I2C Plus) could write UID through NFC.

of It should be done by MCU through I2C interface?

According to NT3H2111 Datasheet,

UID can be read only through NFC

UID can be read and write through I2C

Thank you.

Best regards,

Andy

NTAG devices have a 7-byte Unique ID (UID) programmed in factory which is fixed and cannot be changed.
