1. A single-purpose shopping card issued by a commercial enterprise can be a simple shopping card that can only be used by the merchants who sell the card. There are no credit card restrictions for purchasing this card, such as Shanghai New World Card and Carrefour Card.

2. Multi-purpose shopping cards issued by payment institutions can be simply understood as shopping cards issued by non-commercial enterprises, but issued by some third-party institutions (with the business license of China People's Bank) and can be used by many cooperative businesses (such as shopping malls and supermarkets). According to laws and regulations, credit cards cannot be used for shopping.
