Frequently asked questions

Please use a valid national ID card or passport for your identification. We can't process other documents like driving licences or residence permits for legal reasons. Note: For ID cards, please scan both the front and back side.

Please make sure you use a valid ID document whose expiration date hasn't passed. Note also that the process can only be successfully completed with a valid national ID card or passport. Other documents, such as driving licences or residence permits, can't be processed for legal reasons.

Face recognition records a short video of your face during identification. This is used, among other things, to compare biometric features (eye distance, nose, etc.) of your ID photo against your face. Tips for a smooth process: glasses-wearers should remove their glasses; ensure even lighting (best: daylight in front of a window); hold your phone at eye level so the angle matches your ID photo. If face recognition still fails despite these tips, cancel and restart the process.

A smartphone is required for successful identification. We recommend using the latest version of our iOS or Android app.

Start the age verification flow on the merchant's site. You can choose between our app and a browser-based variant. App: scan the displayed QR code with your phone camera to open or download our app. Register or log in via your mobile number. After successful identification you'll be redirected to confirm the age check. Web: choose register or login, enter your phone number and complete 2-factor authentication via SMS PIN. Note: A successful age confirmation is only possible after identification has been completed.

Start the age verification flow on the merchant's site. The QR code is shown after you've selected the app variant. Scan it with our app's QR scanner or your phone's camera app. When opening the merchant page directly on a phone/tablet, no QR scan is needed and you can initiate verification with a single click.

Each QR code for anonymous age confirmation is only valid for a few minutes for security reasons. To generate a new code, simply restart the process via the merchant's site.

iOS/Apple: check Settings → Safari → Settings for websites → Camera, and ensure "Allow" or "Ask" is selected. Android: Settings → Apps → Tantum → Permissions → Camera → enable "Allow only while using the app". Then restart the identification process.

If your phone camera doesn't auto-focus, you'll be prompted to take a manual shot after a few seconds. Click the camera icon to switch lenses. If it still fails, contact support@tantumpay.com with: phone number (used for Tantum registration), phone manufacturer and model, OS version.

Automated verification and processing of your data usually takes only a few seconds. If a manual review is required (especially outside business hours), there may be delays. We apologise in advance for any inconvenience.

Your personal data is captured digitally and protected by appropriate technical and organisational security measures. Processing takes place in line with the applicable data protection and regulatory requirements. Where personal data is stored, this is done via carefully selected and suitable infrastructure and hosting providers. More information can be found in our privacy policy.

With TantumIdent you identify yourself once via a valid ID document through our app. After that you verify identity or age within seconds via QR code scan. No personal data is transmitted to the merchant – they only receive confirmation of the requested attribute. You stay fully anonymous.

We use your phone number as part of our security protocols for user identification and authentication. By using mobile phone (possession) and PIN (knowledge), strong customer authentication is ensured. Linking your digital identity to your phone lets you access a variety of offers with a single click.

Send an email to support@tantumpay.com with: first name, last name, date of birth, old phone number, new phone number, last four digits of your ID document. Note: After processing, you'll no longer have access via the old number. Processing usually takes 3–5 business days.

Your data is processed and stored according to current regulatory requirements and the highest security standards. If it's no longer needed for the original purpose or the legal basis no longer applies, it'll be deleted – unless legal or contractual retention obligations require otherwise.

If you would like to request the deletion of your personal data, please contact us at support@tantumpay.com. To process your request, we may ask for additional information to verify your identity and prevent unauthorised deletion requests. After successful verification, we will inform you about the handling of your request. Deletion takes place to the extent that no legal, regulatory or contractual retention obligations apply.
