RFID READER HELP Answered
Hello, can anyone help me design an RFID reader which can tell me when something is missing. I would like to build a reader for my file cabinet. I know this is hard but the reader will have to keep reading the files by maybe pinging and when a file is missing from the cabinet an LED will light up and maybe a small readout telling me what file is gone. Cabinet is small only 300mm so if anything is more than 300mm away from the reader it will light up. Can anyone help?
