Haitao payment

Haitao's use of credit cards online abroad is actually safer than using credit cards at home.

When shopping online abroad, you don't need 3 digits on the back of the card, just give the card number, and there is no risk of being stolen. These three-digit numbers are always known only to you, but not to the merchants.

However, Haitao must have a dual-currency credit card, that is, the one with Visa or Master on the back, in order to have a US dollar account and spend abroad.

Every time Haitao spends money and buys things on the shopping website, he only needs to enter the credit card number.

At this time, the bank will send text messages, which means where did you spend a lot of money?

This is a kind of pre-authorization, which gives the online shop the right to apply for payment from the bank after the actual delivery.

The actual payment is made after the product is delivered. If we receive the text message and find that it's not my purchase,

You can call the bank immediately to freeze the money, so the merchants can't get the money!

This not only prevents credit card information from leaking, but also prevents the situation of stealing credit cards.
