When using the ATLAS Access app, we process the following personal data: 

In the access control process 

We will receive your name and e-mail address from our customer, the administrator of the facility which has granted you access via ATLAS to this facility. Your e-mail address will be used to invite you to register your mobile device.

This mobile device ID is device-specific and is used for each mobile access of that device. If you register a new device or the app is reinstalled, a new mobile device ID will be generated for this new installation. 

Once your mobile device is registered, access tokens will be generated and stored at the mobile app according to the locations you are allowed to enter. When you present your mobile device to a reader, an access token is sent, and it will be validated if access should be granted. 

After presenting your mobile device to a reader, feedback to the ATLAS Access app will be sent, containing the location of the door.
