Yes, but only if the gym has a pos machine. Remember to return it next month. Credit card, also called debit card, is a credit certificate issued by a commercial bank or credit card company to eligible consumers. It is a card with name, expiration date, number and cardholder's name printed on the front, and a magnetic stripe and signature strip on the back. Consumers with credit cards can go to specialized commercial service departments for shopping or spending, and then the bank will settle accounts with merchants and cardholders, and cardholders can overdraw within the prescribed limits.

Precautions for credit card use:

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

Generally, the repayment date is 20 or 25 days after the bill date, with the longest interest-free period and the shortest interest-free period.

2. Credit card information protection.

The three key information on the face of a credit card: card number, expiration date and CVV code, affect your card security, especially CVV code, which is as important as password. It is recommended to cover CVV code with correction fluid or sticker, and some people are even worse. Scrape off the CVV password with a blade and remember these three numbers.

3. Diligently handle credit cards, in order to avoid annual fees; Only when the repayment is made on time can the amount be withdrawn.

Generally, you can avoid the annual fee by swiping your card six times. So be sure to pay the annual fee. In addition, we can increase the credit card limit by swiping more cards and swiping frequently. At the same time, being able to repay on time and maintain a good credit record is also a way to improve the credit limit. Moreover, it is also very convenient to pay without a card for mobile phone POS, which belongs to online consumption. Combined with daily offline consumption, a variety of combinations are used.

4. Choose the repayment method that suits you best.

In this information age, repayment methods are diversified, and you don't have to go to bank outlets or ATM to transfer repayment.

5. If the cash flow is not good, or the repayment is delayed due to something, you can call customer service to apply for deferred repayment.

If your funds can't be turned over temporarily, or you are delayed in repayment due to something, don't worry, call the bank customer service immediately and apply for a delay of repayment for one to three days.

6. What if the funds are tight?

When applying for changing the bill date, we should pay attention to calculating the bill date and time, enjoy the longest interest-free period, and relieve the pressure of tight funds. However, this skill is not available 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 once in their lifetime!

7. Say no to all unreasonable charges

Anyone who has unreasonable charges for credit cards can call customer service and bargain with customer service to apply for cancellation of unreasonable charges. If the customer service doesn't agree, you can stick to the complaint in the end and generally win the case.

8. Use credit cards carefully.

Credit card installment interest is very high, even if it is interest-free, the installment fee is not cheap, so use it carefully 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 for those who want to increase the credit card limit as soon as possible.
