A debit/check is a card (made by Visa,
Mastercard, and others. Made avaliable to you mostly by banks) That acts very similiar
like a credit card, but instead of borrowing money from those greedy bastards, money is
automatically deducted right from your checking account instead when you make a purchase. Acts like a cash card.
You need a checking account and cash in your checking account to use a debit/check card. Checking accounts also have a monthly fee.
Visa and Mastercard debit cards can be used to purchase items online. They can also be used with ATM machines to get cash from your checking account.
