Trouble password protecting NTAG I²C plus

[tyler2]

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?  

TIA

Is there anyone on here who I can hire to write this app?

I wouldn't even know where to begin with designing an app in the Android Studio.  Is there another way I can password protect the NDEF tag?

Hi Tyler,

There is a PC demo for NTAG I2C as well, but you have to use it with a NFC reader such as the Identive CLOUD 3700F reader in OM5569-NT322ER | NTAG I2C plus Explorer Kit + reader | NXP .

The application can be found in the following link:

Hope that helps,

Have a great day,
