(1) The card holder may use the identity card as proof of identity and authorization document vis-à-vis public- and private-sector bodies.
(2) Public- and private-sector bodies may use the identity card only to verify identity electronically and not for the automated retrieval or storage of personal data.
(3) Serial numbers, blocking codes and blocking attributes may not be used to enable the automated retrieval of personal data or to link data files. This shall not apply to service providers checking blocking attributes for the purpose of checking whether an identity card's electronic identification function has been blocked.
