Around the University are many hundred card readers which enable University card holders to selectively gain access to restricted areas. Entrances controlled by card readers are called "access control doors".
Turnstiles (such as those giving access to the Main Library) are also controlled by card readers, and this section of the website applies equally to them.
It is your responsibility to keep your card secure. Do not give or lend it to anyone else, and do not reveal your PIN. Doing so constitutes a violation of the University's Computing Regulations.
If you are having problems using your card to access an area, it is likely because you are not authorised to access the area.

Requesting new doors
Fitting a card reader to an existing door is often possible, but needs careful thought.
