When selecting the ARA-M applet via normal AID based selection, it seems one cannot leave it anymore? At least selecting the MF via "80a40004023f00" doesn't work as the applet doesn't provide an implementation of the SELECT (a4) command?

At least on the cards I'm testing with, SW=6D00 is returned (invalid instruction).

What is the intended way to de-select the ARA-M application after it has been selected?

nevermind, one can send a SELECT for another application on the card, and the JCRE will take care of selecting that other applet. No explicit suport needed in the ARA-M applet (or any applet)
