There are lockers at the library on the first floor close to the entrance facing the Tervahovi building and on the second floor closer to the side where Wolffintie is. They are meant for short-term storing of items.
The locks work with any smart card: when you have placed your items in the locker, close the door and touch the lock with a smart card. The locker is then locked and a red light starts to blink. Open the locker by touching the lock with the same smart card. The locker opens and a green light starts to blink.
NB! The locks will open automatically after eight hours!
