A6U48 is a middle range high performance UHF RFID integrated reader. It supports fast tag read/write operation with high identification rate. It can widely applied in many RFID application systems such as logistics, access control, anti-counterfeit and industrial production process control system. The reader A6U48 generates continuously a RF signal in the band 865 - 868 MHz. When a passive tag ( card, sticker or car plate type ), carried by an user or fixed on a vehicle enters in the RF field, generated by the reader, a small perturbation occurs: the tag replies with an encrypted signal, that includes its s/n and more information. These are then detected by the reader which transmits the signal to the decrypting I/F device, that makes them available in wiegand format or activate a relay. The wiegand signal can be read by an Access Control System that gives the final authorization to the user. The reader comes with the corresponding I/F device which has a RF receiver built-in, operating at 433,92 MHz, with a memory for 100 remote controls. The remote control can be used as an alternative means of identification from longer range, with the very high security level given by the 128 bit rolling code, encrypted AES128.
