No danger.

Just call to report the loss and then replace the card.

How to read the credit card slip:

When swiping the card, the merchant will print out the details and tear them into 2 pieces of paper, one of which will be signed by everyone, and the other will be signed by the merchant. The card serves as the cardholder's stub for the person who swipes the card to keep.

The upper part of the stub contains the merchant name and merchant number of the transaction. When you get the credit card signature, you should carefully check whether the merchant name is the same as the merchant doing the transaction at that time to avoid some unscrupulous merchants from using credit cards to save money. The handling fee is based on POS code. (For example, it is clearly a card swipe at an entertainment venue, but the transaction merchant is a wholesale market.)

According to the first 4 digits of the merchant number, you can find out whether there are points for this transaction. For example: The merchant number before this transaction The 4th digit is 3025, which is not included in the list of merchants that China Merchants Bank does not calculate points for. (For the list of merchants that banks do not count, please download it from the official website of each bank, or call customer service.)

The cardholder's stub contains information related to the credit card swiped, such as the acquiring bank, card issuing bank, and card number (in the middle * number processing), credit card expiration date, etc. Among them, the card number and expiration date are confidential information, which may cause risks if leaked, so the stubs should not be thrown away casually.

The cardholder's stub will also list the purchased goods and the price of the goods. If it is a relatively confidential product, the stub should not be thrown away. In addition, it is not ruled out that the merchant may sell the goods. Transaction data, so when purchasing confidential goods, it is recommended not to use credit card transactions. (For example, if a pregnant woman uses a credit card to purchase pregnancy products and leaks her personal information, she may receive many calls promoting pregnancy, lactation, and infant products for several consecutive years.)

In addition, for some shopping malls, if you want to return something, the cardholder's stub can prove that you purchased the goods in that shopping mall.
