Access systems in accordance with various embodiments include techniques for mutual authentication between a passenger that has requested a transportation service and a dispatched vehicle for providing the requested transportation service. Passengers will present a two-dimensional (2D) code to a transaction client associated with the vehicle. The dispatched vehicle uses the 2D code to authenticate the passenger and grant access to the transportation service vehicle.

The invention provides a magnetic actuator including at least two magnets. One magnet is a semi hard magnet and the other magnet is a hard magnet. The hard magnet is configured to open or close the magnetic actuator. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet is configured to push or pull the hard magnet to open or close a digital lock realised with the magnetic actuator. The magnetic actuator of the invention can also be used to realise a valve.

A digital lock including at least two magnets is disclosed. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to open or close the digital lock. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet is configured to push or pull the hard magnet to open or close the digital lock.

The invention provides a digital lock including at least two magnets. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to move to close the digital lock in the event of malicious attack, blocking the intruder thereby the magnets acting as a blocking pin, and the mechanical and/or electromagnetic energy of the attack is configured to move the hard magnet to seal the digital lock from the intruder.

Asset access systems in accordance with various embodiments of the invention utilize a two-dimensional (2D) code that allows a user to gain physical access to and take possession of a key fob, where key fob is understood to represent any wireless device that interacts with a vehicle control system to access, manage, and operate the asset. Users of the system will present the 2D code to a transaction client that grants the user access to the key fob. Transaction clients can reside at various facilities that do not employ humans as part of the asset transfer to the user. Upon completion of the return of the asset to the facility, the user will present a new 2D code to the human-less access system that allows the user to return the key fob or other physical asset to a designated location at the transaction client.

A display unit for a passage control device, having a housing that has a front side, a rear side and an encircling circumferential side connecting the front side and rear side to one another. A display surface is integrated in the front side of the housing. The housing has an optical signaling apparatus that consists of front and rear light bands that are able to be actuated by a computing unit of the passage control device. The front light strip is arranged between the front and circumferential sides and the rear light strip is arranged between the rear and circumferential sides such that the front light strip is visible in a plan view of the front side and the rear light strip is visible in a plan view of the rear side.

A digital lock including at least two magnets is disclosed. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to open or close the digital lock. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet is configured to push or pull the hard magnet to open or close the digital lock.

A locking system is described. The locking system, includes a lock. The lock includes a semi-hard magnet and a hard magnet. The hard magnet is configured to move to open or close the lock, the lock is self-powered using near field communication (NFC), and the lock is digitally controlled using a mobile application.
