About

matecode

Read full description

The use of a digital key for mateco fleet management allows our customers to lock the equipment they rent that they are not currently using, for example after working hours. In this way we can exclude any unauthorised use. The actual locking only requires a bluetooth connection between the matecode application and our machine. This makes it easy to prevent unwanted machine use and significantly reduces the amount of damage caused to or in our machines.
