Everytime I tried writing the [Password] datum to either my xDF2 or the MIFARE DESFire EV2 failed with the message, “Not valid NTAG21x”. Does anyone here know what might be this limitation ? Is password not a common field across all NXP chipset ? I understand that MIFARE DESFire EV2 has a unique organization of their App --> Files, Keys and Config structure. But, thought the password field is an overarching field at the top level of the fields hierarchy. What am I missing ? I bet I am - not sure what.
thanks
