Biometric images and identity data deserve careful handling

The federal data protection law recognises biometric information processed for unique identification, although its scope has exceptions. Before sending sensitive material, identify the organisation, the purpose of collection and the official verification channel for the service you actually requested.

Bank authentication may combine a secret, a device or other credential, and a biometric factor. A claim that every finger photograph necessarily unlocks an account is therefore not a sound basis for action. Open the provider’s genuine application or website independently.

If you already shared information, record what you sent, when and to whom. If you notice an unfamiliar login or transaction, contact the bank or provider promptly through its official channel and ask about restricting access and replacing compromised authentication credentials.
