First of all, it is necessary to understand that the awesome collection code is divided into two different parts: designated collection amount collection and self-service collection.

Collection of specified collection amount: for example, a merchant cooperates and praises it, and then customer B goes to A for offline consumption (eating, shopping, spending, etc. ), merchant A can download the payment code in the background production line, and customer B can directly scan the specified payment code for payment.

Self-service collection: for example, B is a supermarket with a particularly large passenger flow, and the cashier is too busy. At this point, self-service collection is generated in the praise background. At this time, A selects the goods and directly scans the code to pay the corresponding amount, and chooses WeChat, Alipay, credit card and savings card to pay.
