Fees charged to customers

The major fees are for:

Late payments or overdue payments
Charges that result in exceeding the credit limit on the card (whether done deliberately or by mistake), called overlimit fees
Returned cheque fees or payment processing fees (eg phone payment fee)
Cash advances and convenience cheques (often 3% of the amount). Transactions in a foreign currency (as much as 3% of the amount). A few financial institutions do not charge a fee for this.
Membership fees (annual or monthly), sometimes a percentage of the credit limit.
