Hey Guys,

I need to detect de entry of a person in different rooms and i thought about to use one rfid tag to distinguish different persons . Did you know how can i read this tag in a long range since i don’t want to the guy tap the tag to identify himself .

Cheers

Replace the RFID tag reader’s antenna with a door way antenna. Same interface to PC.
