"The Government last week confirmed that the UK's planned ID card is intended to operate as a 'passport lite' that could be used for travel within the European Union, and signalled that Home Office thinking may be moving towards the use of a PIN as a common mechanism for verification. The card's operation as a passport, said Under Secretary of State Andy Burnham, dictates that it will need to use ICAO standard RFID contactless reader technology, while use of chip and PIN would allow it to be compatible with banking and retail systems."
