A credit card PIN is a measure used to protect the security of your credit card account. PIN is the abbreviation of Personal Identification Number, and its Chinese name is Personal Identification Number. Each credit card holder will be required to set a PIN code of more than 4 digits to verify the card holder's identity to prevent others from stealing the credit card.

Protecting the security of personal property is everyone’s responsibility. Setting a safe and reliable PIN code is one of the effective ways to prevent the leakage of credit card information. The PIN should not be associated with numbers such as birthdays, phone numbers, common numbers, etc. that can be easily guessed. Also, try to avoid saving PIN code information in public places or on computers to avoid the risk of information leakage.

If you accidentally forget your credit card PIN, you can contact the corresponding bank or credit card company to reset the PIN and follow the prompts to complete the verification process. In addition, when paying with a credit card, you must remain vigilant and do not disclose credit card information and PIN numbers at will to prevent fraud or theft.
