In what way is a bank credit card different from a store credit account?

The system of bank credit cards operates in much the same way as a store credit account except that the holder is not restricted to making purchases in one place.
    Cards can be presented at any place where the bank card sign is displayed, and that could be at a shop, a service station, a hotel, a restaurant or in fact at all kinds of businesses.
    The sales assistant imprints the card details on to a sales voucher which the customer signs, and the card is then returned to the customer. Each month the bank sends the holder a credit card statement setting out where purchases were made and totaling what is owing. A payment has to be made within 25 days of the date of the statement, but not necessarily the full amount. If the customer pays in full within this time the use of the card does not cost anything. But if he decides to pay only the minimum repayment shown on the statement — $5 or 5% of the outstanding balance, whichever is the greater — he automatically chooses to use the system’s extended repayment facility. The remaining balance is then carried forward and attracts interest at the rate of 2.25% per month.
    Bank credit cards are more versatile than store credit accounts in that they also enable people to obtain cash. Any bank displaying the bank card sign will arrange a cash advance for a card holder, whether or not he is one of their own customers. For money drawn in this way the bank makes a charge at the rate of 2.25% a month, calculated daily from the day the advance is obtained. Details of cash advances appear on the monthly bank card statement.
    The bank credit card system operates entirely separately from cheque accounts, but nevertheless it is a customer’s previous relationship with his bank that is used as a guide to the amount of credit he will be extended. When a card is issued a personal credit limit is imposed indicating the maximum that can be owing at any one time. This is confidential between customer and bank and does not appear on the card.
