Online consumption is actually online shopping, provided that the store supports credit card payment. The parties can choose the goods they want to buy in the store, add them to the shopping cart and pay for them. The payment method is credit card. You can complete the payment by entering the relevant information of the credit card.
Offline consumption can be divided into two ways, one is to brush POS machine consumption, and the other is to scan code payment. The premise of spending by swiping the POS machine is to bind the available credit card with the mobile phone or other mobile payment devices, then call out the credit card and put the mobile phone close to the POS machine to complete the payment. Scan code payment can bind a credit card on WeChat or Alipay, then scan the QR code of the store, select the payment method as credit card payment, and enter the password. Or you can open the mobile phone Alipay or WeChat, show the payment code of the credit card to the merchant, and let the merchant scan the code to pay.
