I think I could understand these guys at Fidelica, if I only knew who sells their product. These guys are the just manufacturers apparently. Does anyone here know who sells their product? The guy at Fidelica says he makes his product for 11 different access control vendors, including HID, but no one I have contacted, including HID knows anything about it. The fidelica guys want to sell me the stuff like I was an OEM access control manufacturer. I am not of course.

I like their tag line though. "Enabling personal, private, conclusive authentication"
