Chicago’s CityKey program launched Thursday.
It's a three-in-one card that serves as a government ID, Ventra card and library card. It also offers discounts all over the city for more than 30 businesses, cultural institutions and sports teams.
Mayor Rahm Emanuel made the announcement Thursday alongside fellow city leaders inside the Field Museum. They called it a victory for the city since it's a program that's accessible to all Chicagoans.
