Rfid Proximity
A simple RFID Reader Schematic.?
I want to build a simple RFID reader, which will power on by a push button. The reader will stay on for 10 seconds emitting radio frequency. Along with the reader a (passive RFID tag) will need to be in close proximity, so that the RFID reader can authorize a locking mechanism. In case where the (passive RFID tag) is not in near proximity, the reader will simple shut off.
Does any one know a link to a schematic, which can help me with this setup?
