what is the difference between credit card and charge card?
Traditionally, a credit card is revolving credit, meaning your minimum payment is less than your balance and you pay interest on the balance you don't pay. A charge card you pay off the ballance every month. This is an old school definition and nowadays the two terms are used for each other often.
No difference. They mean the same thing...charge card is more colloquial (kind of 'slang' in America).
Yep... same thing...
