Are there NFC substitutes that can be programmed?

Question

Do it yourself

I got stuck in the question of buying small modules that, when touched (it is desirable that they were small in size + a small reader), would send text data to the MK and then to the smartphone via the HC-05. Can intercom tablets be programmed? Or would you recommend something else?

Answer 1

Didn't fully understand the question, but I think you need either rewritable RFID or javacard.
