I am trying to write a simple URL to an NFC chip (NT3H2111W0FHKH).  This is an NTAG I²C plus 1K, NFC Forum Type 2 Tag with I²C interface optimized for entry-level NFC applications.  According to NXP, I should be able to password protect the tag in order to prevent unauthorized memory operations.  I am using the NXP TagWriter app on Android but can not seem to protect the data.  Whenever I try to password protect it, it says the chip is not compatible.  Any thoughts?
