Credit cards are one of the great financial instruments of the late 20th
century. The ability to access credit at any time, anywhere in
the world, with something the size of a library card, has proved
to be a boon to consumers, the economy in general and, of course,
credit card companies.
There are various costs associated with credit
cards, including account fees and interest charges on the outstanding
balance. When they hit your statement, make sure you understand
what the charges are for. And remember, credit card companies
can and do make changes to these charges at any time.
