The pay machines of the Bayerische Staatsbibliothek can be used throughout the opening times of the library to settle all fees payable (reminders, reservations, etc.) either by paying cash or using your EC card.
Fees (rent and security deposit) for lockers, transponders and reading-room booths can also be paid at the pay machines.

 

The pay machines are on the ground floor. Viewed from the main entrance it is in the left hallway next to the big main staircase.
