1. The role of credit card security code

Credit card security code refers to the 3-digit number printed on the back of the card. It can be regarded as the ID card of the credit card. It is an important payment voucher for online credit card payment and telephone transfer. It must not be disclosed to others.

After all, many foreign websites only need to know the credit card account number and security code to complete the transaction. There are even some merchants that have signed contracts with banks that can complete phone transfers with only the security code. Therefore, once the credit card is safe, If the code is leaked, it can easily lead to the credit card being stolen.

2. Credit card security code query method

(1) Credit card query:

Just take out the credit card and check the security code on the back, but if the credit card is not around , or it is lost, or the cardholder has cut out the complete code. It will definitely not be found through this method, so the second method must be used.

(2) Telephone inquiry:

Use the reserved mobile phone number to call the credit card service hotline of the card issuer, follow the voice prompts to connect to the manual customer service, and ask the customer service to query the security code. Customer service may help you check after verifying your identity.

However, some customer service will not help with inquiries. After all, a security code is not like a password. If you forget it, you can set it up yourself with the help of customer service. If the customer service finds it, it will be considered a leak.
