The RFU65x RFID read/write device saves space, time, and costs when it comes to identifying vehicles and vehicle parts. This compact device is able to determine the angle from which the transponder responds. The RFU65x also features an integrated logic unit that processes data on the basis of algorithms. This makes it possible to deduce entry detection information plus a vehicle's direction of movement when it drives through a receiving goods door, for example. Unlike other devices, the RFU65x does not require any additional external antennae. Not only does this cut down on costs, it also simplifies and accelerates application processes in logistics.
