The validity period of the credit card is displayed under the 16 digit card number of the credit card. Some cards only show the expiration time, while others show the interval between issuance and expiration.
If the number below the card number is an interval, such as 02/ 10-02/ 15, it means that the card was issued in February 20 10, and will expire at the end of February 20 15; If the number below the card number only says 02/ 15, it means that it will expire at the end of February.
skill
1. When the validity period of the credit card is entered, the month is after the previous year, such as 02 15.
2. The validity period of the credit card can only be seen after you get the card, and there is no other channel to inquire for the time being.
3. The validity period of the existing credit card remains unchanged before the extension, and you can still use it normally before the expiration of the validity period of the card.
