There are several reasons why China UnionPay Express Pass cannot be used. Please take a look at them accordingly. First, the types of coupons are not used in the right place. Food coupons can only be used in restaurants, and supermarket convenience store coupons can only be used in supermarkets or convenience stores. Shopping mall coupons can only be used in shopping malls.

Second, the amount used did not reach three times the face value, which made the coupon unable to be written off.

Third, the users do not participate in the activities. It is recommended to ask the merchant whether to participate in the activity before using it.
