Integrated QR-reader access control with user management via booking app. 

QR-codes are one of the most adaptable, flexible, affordable & integrat-able form of 'throw away' access control options available. The QR-code can be saved on a user's phone via email confirmation of a booked service ie: parking or rental service. The QR code can also be printed on paper and shown to the QR reader for access. QR-codes are dynamically generated and sent to the user booking the service so they're ideal, and intended, for 3rd party on-demand booking services such as pre-book parking where temporary access is required.

PIN code access control with time/day/date restrictions  – managed online.

Remotely managed restricted user access is critical to maintain security of any building or car park. In particular, if the parking operator is a 3rd party service, it's important that users sent to the car park are restricted to only the time of their booking with event logged history to add another layer of visibility.

Handsfree vehicle access control with long-range adhesive RFID tokens.

Long-range RFID for vehicles is a simple approach to managing vehichle access for permanent users of a car park. Compared to ANPR, where users are required to have their vehicle on a whitelist to avoid parking charge notices (PCN), an adhesive ID token is mounted to authorised vehicle windscreens. The token has a unique ID which is managed using our web-based management platform. Vehicles can still be restricted by time/day/date restriction. All users entry events are logged online for admin use.
