Because of immigration status, financial limitations, youth, or other reasons, some people cannot obtain valid ID cards from the state or federal governments, or else run into obstacles when they try to do so. A municipal ID card is an alternative. In Philadelphia, it would help residents access basic services, such as groceries from food pantries, treatment for drug addiction, and entry to City Hall and the Municipal Services Building. In Chicago, the cards also offer discounts on medical prescriptions and museum admissions and double as library and public transit cards.
