When a person is poor and in need of financial assistance, the state will sometimes provide funds for the purchase of food. The economically depressed person will be issued a "Link Card" which he or she can use as a debit card when purchasing food.
Unfortunately, the definition written by "makinde" was not correct. The Link Card is not for people in "rat infested" areas, nor is Chicago a poor excuse for a city. Further, Link Cards are not used only by "lazy" people.
Makinde needs to remove his or her prejudices before providing a a definition.
This link card works like a debit card. Use it to purchase food.
