Hello David,

Please note that Android Studio provides app builders with an integrated development environment (IDE) optimized for Android apps. Within IDE you can create an application and after, you can import TapLinx SDK into your application.

NTAG 424 DNA can be configured as Read-Only with help of SDK. Please check APPLICATION NOTE - NTAG 424 DNA and NTAG 424 DNA TagTamper features and hints, chapter "6.15 Write to CC - using Cmd.WriteData, CommMode.PLAIN". Two things to do to transition into Read-only life-cycle:

• Write read-only byte into CC file (E103)*
• Set WRITE access rights of NDEF file to 0xN (N = number of any key from 0 to 4, so write access for the ones knowing that key) or 0xF (no WRITE access for anyone)

* In order to write/change data to CC File, you need to Authenticate before with key 0x00.

Method to use to change access rights:
changeFileSettings(int fileNumber, NTAG424DNAFileSettings fileSettings)


Best regards,
TapLinx team

Dear Parthsaradhi,

For the case when you already successfully executed the transition with Pegoda reader:
With help of RFIDDiscover SW tool and Pegoda, you can check APDU exchange in Log window and apply similar exchange to your firmware. Most probably you will need to insert ISO14443 communication APDUs into Host -> Reader APDUs. For that a reader shall include such instructions.

Best regards,

Dear Varun,

This forum is intended for TapLinx SDK only. We would suggest to read 3rd party documentation. Maybe https://learn.microsoft.com/en-us/samples/xamarin/monodroid-samples/cardreader/.

Dear David,

Please note that this is purely TapLinx related forum. Question is going a bit beyond our reach. Please contact local NXP Sales representative and will guide to answers for your application. In short Key ownership is each project / application specific. It is usually one party. So application owner has knowledge of the keys, online and the ones on chip.

Best regards,

Dear Robert,

in the library .zip file there are .jar files which you can include into your project. We encourage you to use latest one (as of today) 3.0.0.

Dear David,

For the start we would encourage you to go through Datasheet, Application Notes and search web for Cryptography articles.

Errors are described in Datasheet, page 48. 0x91AE: Current authentication status does not allow the requested command. Probably, you are not using the valid key for Authentication. Or you did not select NDEF Application upfront.
