We use your mobile phone number as part of our security protocols for user identification and authentication. As part of each payment or identification process, the respective user authorizes the process via our app. This app, which is protected by a personal PIN and the use of biometric data (optional), must be installed on the user's personal cell phone.
Our system ensures that only you, as an already identified and age-verified person, are granted access to offers with so-called closed user groups. By using two elements, your cell phone (possession) and your Tantum PIN (knowledge), strong customer authentication can be guaranteed. Linking your digital identity to your cell phone allows you to access a wide range of offers with just one click.
