Abstract
A device is described that includes a first microprocessor configured for interfacing with a digital access control backend, and a second microprocessor configured for dedicated communications with an access control manager device backend. The first microprocessor is a master device that controls the operation of the second microprocessor as a secondary device. The proposed device is configured for operation of the first microprocessor and the second microprocessor at low clock speeds and to maintain a hash segregation between locally received data sets and data sets transmitted to an external authentication system.
