1. You Scan Them: The merchant displays a static QR code. You open WeChat, tap “+”, select “Scan,” scan their code, enter the amount, and confirm with your password or Face ID. This is common with smaller vendors.
2. **They Scan You:** You open your WeChat Wallet and present your personal payment QR code (which changes every minute for security). The cashier uses a scanner to read your code, and the amount is automatically deducted. This is standard in supermarkets, restaurants, and larger stores. * **Peer-to-Peer Transfers:** You can instantly transfer money to any of your WeChat contacts directly within your chat window. This is used constantly for splitting bills, paying back a friend, or sending money to family. * **In-App Services:** WeChat features "Mini Programs" (小程序), which are essentially apps within the app. You can use WeChat Pay to order food delivery, book movie tickets, hail a ride, pay utility bills, and access government services without ever leaving WeChat. * **Formality:** Using WeChat Pay is neutral and appropriate in almost any transactional context, from a formal restaurant to a street vendor. The act of saying "I'll use WeChat Pay" (我用微信支付 - wǒ yòng wēixìn zhīfù) is standard and common.
