The credit card doesn't have a password. Can someone else swipe it if they find it?

Yes. Credit cards can also be swiped without a password, because if a credit card does not have a password, it can complete the transaction by signing. Moreover, if the small-sum secret-free and visa-free function is enabled, when the single consumption amount is less than 1, yuan, the card can be directly "flashed" near the induction area of the POS machine without entering a password and signature, and the payment can be completed. Therefore, it is better to set the transaction password for credit cards, because if there is no password, it is easy to steal the card. And at that time, because the customer does not have a password, the responsibility may still be borne by the customer, and the stolen money may not be recovered, and the customer will be responsible for repayment.

Precautions for credit card use:

1. Pay attention to two dates: billing date and repayment date

Generally, the repayment date is 2 or 25 days after the billing date, and the credit card is swiped one day after the billing date, with the longest interest-free period, and the credit card is swiped one day before the billing date, with the shortest interest-free period.

2. Protect the information on the card surface of the credit card

The three key information on the card surface of the credit card, namely, the expiration date and the CVV code, affect your card safety, especially the CVV code, which is as important as the password. It is recommended to cover the CVV code with correction fluid or sticker, and some people are even worse. Just scrape off the CVV code with a blade and keep those three numbers in mind.

3. swipe your card frequently to avoid the annual fee; Only when you repay the loan on time can you withdraw the amount

Generally, you can avoid the annual fee if you swipe your credit card for six times. Therefore, we must brush out the annual fee. In addition, we can increase the credit card limit by swiping more cards and frequently. At the same time, we can repay on time and maintain a good credit record, which is also a way to increase the credit limit. Moreover, it is also very convenient to pay without a card for mobile POS, which belongs to online consumption. Combined with daily offline consumption, multiple combinations are used.

4. Choose the repayment method that suits you best

In this information age, repayment methods are diversified, and it is not necessary to go to a bank outlet or an ATM to transfer money.

5. If it doesn't work, or the repayment is delayed due to something, you can call customer service to apply for deferred repayment.

If your funds are temporarily unable to turn over, or the repayment is delayed due to something, don't worry, call the bank customer service immediately and apply for an extension of repayment for one to three days.

6. what should I do if the funds are tight? Apply to change the billing date and extend the interest-free period

When applying to change the billing date, you should pay attention to calculating the billing date time and enjoy the longest interest-free period to relieve the pressure of tight funds. However, this skill cannot be used every month. It is said that some banks can only apply for change once every six months, some banks can only apply for change once a year, and some banks can only change it once in their lifetime!

7. Say no to all unreasonable charges

Anyone who has unreasonable charges on a credit card can call customer service and bargain with the customer service to apply for cancellation of unreasonable charges. If the customer service disagrees, they can insist on complaining to the end and generally win.

8. Use credit card installment with caution

The interest rate of credit card installment is very high, even if it is interest-free, the installment fee is not cheap, so use it with caution, and don't let the bank earn a dime! Of course, except for those who can't repay the credit card arrears on time under special circumstances, except those who want to increase the credit card limit as soon as possible.

In case of stolen credit card, you can ask the merchant to sign the bill and identify the person who swiped the card by signature, and ask for refusal or refund. The premise is that you have relevant copies or photos, record your credit card and then sign the pattern for comparative evidence.

2. Password.

The bank says that the consumer password is optional, but at the same time it says that password transactions are regarded as personal transactions. That is to say, as long as the password is used, in case someone reads it, it is regarded as your own brush to make a fake card or steal your card with the password. Banks and businesses are irresponsible.
