Claim 11:
12. A access control assembly attachable to a door of an enclosure, the access control assembly comprising:
a latch configured to engage a catch affixed to an inner portion of the enclosure when the access control assembly is attached to the door of the enclosure, wherein the latch engaging the catch secures the door in a locked state;
an actuator configured to electronically open the latch to open the door of the enclosure;
a latch controller;
a credential interface configured to receive an electronically provided access credential;
a communication interface configured to communicate with a server over an electronic network; and
wherein the latch controller is configured with instructions to:
receive the access credential from the communication interface;
responsive to receiving the access credential:
store an indication of the access credential in a memory device;
query the server over the electronic network as to whether the access credential is authorized to access the enclosure;

trigger the actuator to open the latch when the server indicates the access credential is authorized to access the enclosure; and
when the server indicates the credential is not authorized to access the enclosure or when the communication interface is unable to communicate with the server to authorize the credential:
require a secondary credential to access the enclosure;
receive the secondary credential to access the enclosure;
trigger the actuator to open the latch based on receiving the secondary credential;
store, in the memory device, a record of the latch being opened together with the secondary credential; and
provide the record to the server at a next time the communication interface communicates with the server.
