The Bike and Ride Box app is an electronic booking and access system for secure bike parking systems. The bicycle parking systems serve both long-term tenants (e.g. week, month, year) and spontaneous users (e.g. daily use). Using a PIN code, the system reliably opens every bicycle parking system that is controlled via an electronic door opener. Alternatively, depending on the location, a QR code or an RFID card can be used as an access medium. The user can book the parking space in advance using the Bike and Ride Box app.
