Interesting. But the iclass ii hf runs on the 15693 and 14443-b standards. Presumably that is why it beeps only once. My NExT’s xNT is 14443-A and 14443-B compatible.vthe exact badge I have is an iclass DF by reading the badge, but I can’t find any good information on it. Theoretically the xIC would have worked. Can I get one custom made? Is there any leftover stock? I keep reading that the vivokey spark can be used for access control… how would I set that up or is it only for the flex? I didn’t really do enough research on the spark. Didn’t know it was basically useless for now.
