"Offline access" is a feature that allows locks that are (temporarily) not connected to the IQ. This can happen for a number of reasons, including a power outage that causes the IQ to switch off temporarily
Offline Access by no means gives the ability to the holder of the tag to open doors that the user is not authorized for. In case the lock cannot validate the tag and its access rights in the database, the lock will fall back on the 'Offline Access' validation which means that if the presented tag has Offline Access and is included in an access group that has access to the lock the tag is presented to, the lock will validate the tag and provide access to the holder of the tag. Due to the storage capacity of a lock, and depending on the firmware of the lock this feature can be assigned to a maximum of 39 Users / Tags. Please note that Offline Access has 24/7 accesses to a door if the lock falls back on the Offline Access validation, even if in the access group the access of that Tag is limited to a specific time frame. In other words: access group time restrictions do not apply to Offline Access when the IQ has no connection to the lock or to our database.
Offline Access can be assigned to the user by editing the user in 'People' > 'Keys' and checking the box 'Offline Access' for the credentials you want to allow it on. This means you can assign this right to a physical tag and digital key separately.
