Generally, the seller will initiate "setting advance payment" and scan "buyer's payment code" for fear of overdue payment.

This operation is overtime/convenience store popular,

For convenience (input Alipay account), vendors also provide "receiving code" (QR code) for buyers to scan "seller's receiving code".

If it is a single price, the seller can set the amount. When the amount is uncertain, it is necessary for the buyer to consciously enter the "amount" for the seller to confirm before paying.

As for "flower shop payment" and "credit card payment", the payee needs to pay the handling fee, which has nothing to do with the buyer.

Sellers open more payment methods to facilitate consumers.
