On the front of the credit card, there is a line of numbers between the card number and the name, and the first year is the first application date of the card. It shows 2009, which means this card was first issued in 2009. The number in MM/YY is the expiration date, for example, 12/ 14, which means it will expire in February 20 14. The validity period of Jinsui Credit Card (including Jinsui Platinum Credit Card) is calculated backwards based on the date of business card printing.
