During an identification process, certain security features (e.g. holograms) and information on the identification document used can be checked to prevent fraud. Such a check is necessary due to the regulatory requirements of the Federal Financial Supervisory Authority (BaFin), in particular in order to complete an identification process in the financial sector successfully.
For this purpose it is mandatory that the required information and fields in the ID document are visible. This is why we always advise against blackening out information, covering or using adhesive tape because the verification may otherwise not be completed successfully.
