The Bluetooth Long Range RFID Reader can read up to 20 meters and the reading distance is adjustable. It has strict 60 degree direction and can penetrate through the cars’ anti-explosion metal film. Besides, the long range reader uses the infrared synchronous communication technology and microwave technology which can realize the non-stop entry and exit parking system, non-stop counting system for vehicle, non-stop attendance system for bus and so on.
The long range RFID reader sends out 60 degree infrared signal including wake-up code and machine code. As soon as the long range RFID transponder enters into the infrared signal area, it will be waken up to sent its internal code and at the same time send the machine code to the RFID reader. When the RFID reader receives the internal code, it will validate the machine code and upload it to the host computer if they match with each other and if not it will delete the machine code directly to avoid the interference from cars in the vicinage lane or following cars.
