APDU Command Type Identification

To identify proprietary and interindustry commands, use the isISOInterindustryCLA method. This call returns true if the CLA byte encoding corresponds to the interindustry space, or false if it corresponds to the proprietary space.

//Applet's process method
public void process(APDU apdu) {
	byte[] buffer = apdu.getBuffer();

	// check SELECT APDU command
	if (apdu.isISOInterindustryCLA()) {
		if (Applet.selectingApplet()) {
			return;
		} else {
			ISOException.throwIt (ISO7816.SW_CLA_NOT_SUPPORTED);
