Hi Experts,

Does the Latest TapLinx Android SDK support reading NTAG 424 proprietary file data?

Actually in my project need to implement reading NTAG 424 proprietary file data.

Thanks!

Hello gopesh,

Yes it supports. You can do it with following API:

• ISOReadBinary - command requires manual encryption and MAC-ing of payload. And also you need to select NDEF file upfront with ISOFileSelect
• ReadData (with CommMode.FULL) - recommended

• byte[] readData(int fileNumber,
                  int offset,
                  int length,
                  MFPCard.CommunicationMode commMode,
                  byte readAccess,
                  byte readWriteAccess)

In both cases you need to perform mutual authentication first, as default Read Access Rights to Proprietary file are granted for Application Key nr. 2 (check datasheet of NTAG 424 DNA) only.
