Proximity access cards used to be the best and most cutting edge form of access control. But what if the access points could actually open by themselves by just walking near them.

I found this company online that can read a FOB in your pocket, or in your car that will automatically let you into certain access points. Star Trek anyone?

Anyways, we did not use this technology since the contract was already awarded by the time I found this info. I don't know how well it works or what it costs.
