Class TagTechnology

java.lang.Object
com.codename1.nfc.TagTechnology
Direct Known Subclasses:
IsoDep, MifareClassic, MifareUltralight, NfcA, NfcB, NfcF, NfcV
public abstract class TagTechnology extends Object

Common surface for the low-level technology views attached to a Tag -- IsoDep, MifareClassic, MifareUltralight, NfcA, NfcB, NfcF, NfcV. Application code never instantiates these directly -- they are returned by accessors on Tag.

Each technology exposes a [#transceive(byte[])] method that fires raw bytes at the tag and returns the response. The exact framing depends on the technology -- IsoDep expects ISO 7816 APDUs, MifareClassic expects single-block commands, etc. Always defer to the technology- specific subclass docs.
