identity cards are also getting smarter. many countries already have a system which requires their citizens to carry identification cards. these cards usually include personal information such as name , address , and birth date as well as a personal identification number. however , in the near future , these cards will also contain a microchip , which will be able to store a lot more information. using this technology , one cards will be able to replace your driving licence , student card , medical card , library card , credit card , birth certificate and most of the other pieces of id that we have to carry around with us.
