1.How does our lock work?

Every lock has a specific ID that can only be changed with special device that is connected to the lock directly. The cards are only programmed that way that there is a date until they are valid for being used as key, so if you steal a card and try to use it after the time of booking, the lock denies access even if the card has worked before simply because the date passed until it’s been declared as being valid.

Using a regular card-reader/-writer the values are secured using cryptographic techniques like signatures and/or encryption.
