So far the only thing I’d like to do is clone my HID Prox id (apartment access control) to the chip. I have a t5577 coin that I cloned and it’s in my phone case, but I’d love to have bio entry. I got the Flex mostly for the OTP feature to be fully honest. I’m not super familiar with smart cards and what they allow, so I’m open to many ideas. At this point I think I may be getting a flexNT or NExT (cus blinkies!) but I’ve never come across an NTAG and not sure where it’s common.
tl;dr — HID Prox ID clone and whatever else may be possible for cool stuff!
