Checkpoint is a digital check-in solution.
It is very easy to create a Checkpoint. Your checkpoint always comes with a QR-code that you can either print or distribute digitally. The creator of a Checkpoint can keep track on users than scan the QR-code.
A user checks in by scanning the QR-code that belongs to the Checkpoint. Only the first time a user scans a Checkpoint, he is asked for a password. After a scan the device ID, location, time and date are stored for that particular user.
