C

With a VISA card in your hand, the world opens up to you. With more than 24 million places across the world accepting VISA, you can use your VISA card instead of cash to pay for your everyday purchases—whether you are shopping at the grocery store, dining at a restaurant, filling your car with petrol or buying the perfect gift on your travels. You can even use it to get cash from more than one million ATMs around the world.

To avoid even that inconvenience, you can take the following basic precautions:When you get your card:

Sign the signature panel immediately;4BIf you have been given a PIN(personal identification number) to use at a cash machine or in shops, memorize it—never write it down;

If you choose your own PIN, or change the one you were given, avoid obvious choices such as your date of birth or telephone number;

Do not tell anyone your PIN;

At home

Keep your sales and cash machine receipts and check them against your card or bank statement;

If any amount is incorrect or you spot a transaction you did not make, call the bank or other organizations that issued your card immediately;

Keep a list of your card numbers, along with the telephone numbers you should call if they are lost or stolen.

In the shop

Check the sales slip to ensure the amount is correct and the total has been filled in before you sign;

Make sure the retailer gives the card back to you, along with your copy of the voucher(收据);

Keep your card close to you—be ware of pickpockets(扒手);

Do not leave your card in your car’s glove compartment.

Telephone and mail order shopping:

When you place an order over the telephone or by mail, give your card number only if you are confident about the company’s reputation;

You might be asked for your VISA card security code—the three digits at the end of the card number printed on the signature panel. Give the seller that code but never give your PIN.
