Access system for a building

摘要

The system has a transmitting-/receiving device i.e. printed circuit board assembly, provided in building doors (2, 2') i.e. access door, of a building (1). The transmitting-/receiving device receives an identification code of a key (4) when the key arrives in a detection area of the transmitting-/receiving device. A verification device verifies whether a valid access authorization for the building doors exists for the received identification code. A locking device unlocks the doors if the valid access authorization for the building doors exists for the received identification code. Independent claims are also included for the following: (1) a method for operating an access system for a building (2) a computer program product having a computer program unit to implement a method for operating an access system when the computer program unit is loaded in a processor of a transmitting-/receiving device and/or a verification device and/or key and/or a control device and/or a communication device (3) a computer readable data storage unit having a computer program product including a computer program unit to implement a method for operating an access system when the computer program unit is loaded in a processor of a transmitting-/receiving device and/or a verification device and/or key and/or a control device and/or a communication device.
