Interface ISO7816

    public interface ISO7816

`ISO7816` encapsulates constants related to ISO 7816-3 and ISO 7816-4. `ISO7816` interface contains only static fields.

The static fields with `SW_` prefixes define constants for the ISO 7816-4 defined response status word. The fields which use the `_00` suffix require the low order byte to be customized appropriately e.g (ISO7816.SW_CORRECT_LENGTH_00 + (0x0025 & 0xFF)).

The static fields with `OFFSET_` prefixes define constants to be used to index into the APDU buffer byte array to access ISO 7816-4 defined header information.
