Hey guys I am new here and I just got myself a Arduino Ethernet and can't wait to do something with it. So I am going to make an access control for my house door. I need to make it in a way that when I walk to the door, it automatically unlocks when I am 3-4 meters away. I found OpenBeacon active RFIDs that are compact and easily fit my wallet (I hope). However I don't know what sort of reader I should buy so I can connect the reader to Arduino and control the door luck by Arduino.
OpenBeacon sell a reader, but it is USB and I am pretty sure I won't be able to connect USB to arduino and read the data off the USD receiver. Any advice would be greatly appreciated. thanks
