Hello,

Thank you for using our products.

To remove the password you need to authenticate and configure the respective page. Please take a look at section 8.8.1 Programming of PWD and PACK of the Datasheet.

Could you please clarify which reader are you using?

Hello sir my apologies but, I referred to the Reader you are using. As you can see in our portfolio: https://www.nxp.com/products/rfid-nfc/nfc-hf/nfc-readers:NFC-READER

There are several readers available, and some of them can be used with our NFC Reader Library. This library does include some functions to interface with NTAG 213 and, to correctly remove or modify the password once authenticated.

Hello sir,

Unfortunately, I don't have an example for setting a password using an Android device. My recommendation would be to please take a look at the Datasheet commands, along with the NTAG 21x features and hints document.

We recommend to please take a look at our TapLinx SDK from Android which has a set of functions based on Android to read and write into tags.
