Charge cards are a little different from credit cards.  Charge cards usually have no charge limit, unless the local banking regulations impose one.

You can usually charge as much as you want, but you are required to pay off your entire balance when your bill arrives.

Charge cards usually have relatively high annual fees.  If you don't pay your charge card bill in full, your account may be suspended and you will be charged interest rates on the outstanding balance as well as any additional fees.  Your bill may also be sent to the collections department.
