NfcV - how to getHistoricalBytes, like in NfcA?

In NfcA standard there is an android.nfc.tech.IsoDep class. It has a method called: getHistoricalBytes(). How to get this functionality in NfcV standard? IsoDep class doesn't work here. Any ideas? Help will be appreciated.

Solution

  • NfcV (ISO15693) technology doesn't has anything like HistoricalBytes. HistoricalBytes only exist in the NfcA (ISO14443-A) standard.

    The only static thing you can read from a NfcV Tag is the UID and the DSF-ID (data structure format identifier, often not used). You get it by casting your tag object to an NfcV object and then call getDsfID()
