Claim Text:
1. An access control system comprising: a plurality of stationary containers, each stationary container comprising, a container identification feature, an interior space, a locking device which is selectively releasable to facilitate an access to the interior space, and a stationary security module arranged inside the stationary container, the stationary security module comprising at least one integrated circuit, an authorization module, and a security key generator configured to generate a security key; a mobile authorization key supply device comprising a storage device and a communication interface, the communication interface being configured to directly or indirectly supply an authorization key to the authorization module; a remote computer system comprising an authorization key generator, the remote computer system being configured to communicate with the mobile authorization key supply device so as to transmit the authorization key to the mobile authorization key supply device; a one-time key configured to be preset for the security key generator; a one-time authorization key; a permanent key preset for the security key generator; a supplied permanent authorization key; a module configured to determine a loading state of the stationary container; a master security key; and a master authorization key configured to be preset, wherein, the authorization module is configured, to compare the security key with the authorization key and to generate a signal to release the locking device if a match between the security key and the authorization key is determined, to compare the one-time key with the one-time authorization key and to generate a signal to release the locking device if a match between the one-time key and the one-time authorization key is determined, to compare the permanent key to the supplied permanent authorization key, and, if a match between the permanent key and the supplied permanent authorization key is determined to exist and if the authorization module determines that the locking device is not locked by the one-time authorization key, to generate a signal to release the locking device, and to compare the master authorization key to the master security key, and to generate a signal to release the locking device if a match between the master authorization key and the master security key is determined and if the module determines that the stationary container is not loaded, the mobile authorization key supply device is configured to be operated in an online mode where a communication between the authorization key supply device and the remote computer system is presumed ensured, and an offline mode where the communication between the authorization key supply device and the remote computer system is not ensured, and a communication feature is linked to each container identification feature, the container identification feature linked to the stationary container being determined using the mobile authorization key supply device, and the authorization key that is assigned to the container identification feature being queried, the communication feature being configured to selectively preset the online mode or the offline mode for the stationary container which corresponds to the container identification feature.
