Contactless RFID

Systems with PIN pads, magnetic stripe readers or fingerprint sensors are often used for access control. However, contactless alternatives are generally more convenient, just as safe and much more hygienic – and therefore make sense, especially in connection with the current spread of the new corona virus. For example, if an infected person transmits viruses to the surface of a PIN pad, they can adhere there and survive for several days. Other people can then pick up viruses simply by touching the buttons. If the viruses pass from the fingers to the mucous membranes, they too can become infected. Germs also collect in slots for magnetic stripe cards and are indirectly transmitted via the cards. Access controls with contactless RFID readers effectively prevent this type of smear or contact infection.


RFID solutions

RFID-based readers in the HF range represent one option. In this case, gates and barriers are triggered via special chip cards or key fobs equipped with transponders. Thanks to secure cryptographic encryption, the cards cannot be copied. Only users registered in the system are granted access. When the card or transponder is a few centimeters away from the reader, the RFID unit reacts and sends an impulse to the gate or barrier control system. UHF RFID readers offer particularly convenient access control. Transponders mounted on the windshield can be read from a distance of up to 10 meters. This means that vehicles do not have to stop for authentication, but can drive directly through the automatically opening barrier. This is just one example.  Contactless entrance is coming to all aspects of business.
