After spending abroad (including taking a taxi), just swipe your card and sign your name. Be careful not to overdraw ~
Also, the seven digits in the signature file you mentioned are very important, which is equivalent to your confirmation code or verification code.
The most important thing about a VISA card is the card number+the 7-digit code at the back+the expiration date (the front of the card is in the form of month/year)+your name.
Also, the biggest advantage of using this card is that it is convenient to consume. Just pull down the number and sign it. Take the invoice/bill/receipt with the amount and purpose of your consumption and the address on it. Please keep it.
Afraid of being stolen? Yes, the bank that issued your card requires you to send you a monthly consumption list. The time, place (store name, address) and amount are all written in detail. If you find any problems, you can find a bank to help you audit the accounts within 14 days, which can reduce the losses.
How to use cash urgently? VISA can also be used to withdraw cash from supported ATMs. Use the same method as UnionPay card. It also uses passwords. The passwords of the main card and the auxiliary card are different. But the disadvantage is ... the handling fee is too high ... NND is very upset at the thought of this. (about 4%)
You don't need to show your visa when you go there. Yes, VISA is also an ID. Multiple ids are very useful in the United States. If you take a driver's license or something, you can use Chinese. Then, add your passport and health card (or work permit) and you will have 4 photos. Basically, you can do anything. You should know that some BT services ... actually require you to show more than three PID's ... such as when Western Union withdraws money. ...
In addition: the cardholder's name is the cardholder's name. That is, you pull it.
The cardholder's signature is the cardholder's signature.
What is the difference? In fact, the number 1 (cardholder's name) is written neatly, and the number 2 (cardholder's signature) is written casually, because the signature of your future consumption is based on the number 2 (cardholder's signature). If you find it very different, you will think it is fake. If you want to rewrite or show your ID card, the signature on the back of the card should be consistent with the number 2 (cardholder's signature).
Unfortunately, I don't know how to map it. I used the VISA card of China Bank. I don't have my bill or bank statement at hand. Hehe, I can't provide you with more physical objects. Please consult an expert again.
Completely original by myself, welcome to reprint. But please leave my name and respect my work LOL.
