VIZpin is not paired with your phone like a Bluetooth speaker or carkit and will never require you to enter a PIN. Instead, all communication between your phone and VIZpin is done through the VIZpin SMART app.
When you want to gain access with your phone you will receive a unique Location ID- these are automatically generated and secure. You will type this Location ID in when you register as a new user on the VIZpin app. This will then send an email to the account manager stating that you are requesting access. The manager will then be able to grant you access and you can begin using your keys!
