The regulation stipulates that all identity cards issued in the EU must have the credit card format, have a machine-readable zone (MRZ) and meet the minimum security requirements of the ICAO (International Civil Aviation Organization). In addition to the already required biometric passport photo, two fingerprints will also be stored on the RFID chip of the ID document. The new EU requirements are to be transposed into national laws in the as of yet 28 member states by 2020. The older ID cards will expire after five to ten years. Senior citizens over the age of 70 will be subject to a longer transition period. Two fingerprints are also to be stored on children’s identity cards. These should be valid for a maximum of five years.
