NetCode Explained


What is NetCode?

NetCode is the smart way to generate time-sensitive codes which can allow temporary access via the Codelocks API, the K3 Connect App or through the online NetCode portal. Set codes for a specific date, time and duration. Send codes via email or SMS*, the code will not work outside a designated timeslot.Using time-sensitive codes is a more secure way to grant access as the code will not work outside a designated timeslot. Issue codes to visiting service engineers, delivery personnel and short/medium-term locker rental.
