3. The credit card has an expiration date, which is located below the card number on the front of the credit card. It is displayed in month/year form. For example, it is displayed as 10/22, which means that 10 will expire after 22 years.
If the credit card is not opened before the expiration of the validity period, the card will automatically become invalid after the expiration.
