Abstract
Systems and methods for key card authentication are provided. The system may involve multiple simple key card readers connected to a central, local device over a shared data bus. A key card reader may receive an identifier from the key card and transmit it to a local device. The local device may generate a challenge/response pair and send it to the key card reader. The key card reader challenges the key card and determines whether the key card's response matches the expected response. The system uses minimal bandwidth on the shared data bus network.
