I'll send you one as a toy, don't worry about the cost. I ordered them from Korea for next to nothing, along with a shitload of professional NFC products for a security job I was doing. Then did nothing with these. The pro products wouldn't help you, but these standalone boxes are easy to use. You can do card plus pin, just pin, or just card. Programmable. Good look on the Engrish, but really it's not that terrible. I think it's a one second relay close then open, so good for door locks, garage doors, etc.
