(12)The mobile driving licence should contain not only the information reported on the physical driving licence, but also information enabling the verification of the authenticity of those data. However, it should be ensured that even in the case of verification, the amount of personal data made available is restricted to what would be reported on the physical driving licence and what is strictly necessary for the verification of the authenticity of such data. Moreover, unless allowed under Union or national law, the data necessary for the verification should not be retained after the verification has taken place. Member States should ensure that physical and mobile driving licences issued to the same person are equivalent as regards the rights and conditions under which that person is authorised to drive, and as regards the duration of the administrative validity of the driving licences, as set out in this Directive.
