The red card is a voucher, and the blue card is a coupon.

After the red card is recharged, it will be displayed on the credit card interface of the backpack. Red cards can be used to purchase gold coin items in the mall. (Except for certain items, such as golden pumpkins) Vouchers cannot be used in exchanges.

After recharging the blue card, you can also see it in the credit card interface. But don’t pay too much attention, your coupons will not be used up. It gives you more than you use, just to stimulate your consumption.
