Street vendors, food stalls, and market sellers use static or dynamic QR codes that customers scan with WeChat to pay. The customer enters the amount and confirms with a password. This low-cost setup enables cashless transactions without dedicated hardware.

At supermarkets, convenience stores, or transit gates, customers display their WeChat Pay payment code (barcode/QR) to be scanned by the merchant's POS system. For amounts under 1000 RMB, the payment is often password-free for speed. This streamlines high-volume checkout lanes.

Online merchants and Mini Programs integrate WeChat Pay SDK to allow users to pay within the WeChat environment. The user selects WeChat Pay, confirms the amount, and enters their password. This provides a seamless payment experience without leaving the app.

International tourists in China and Chinese tourists abroad use WeChat Pay to pay in multiple currencies at supported merchants. The system handles currency conversion and settlement, reducing the need for cash or foreign cards. This enhances convenience for global travelers.

Businesses offering recurring services like membership subscriptions or highway tolls use WeChat Pay's password-free withholding API to auto-debit users' accounts. Users authorize the merchant to deduct funds automatically on a schedule. This reduces churn and ensures timely payments.

WeChat Pay charges merchants a small percentage fee per transaction. This is the primary revenue stream for the platform. Fees vary by industry and transaction volume.

WeChat Pay offers additional services such as marketing tools (cash vouchers, store coupons), data analytics, and cloud services. Merchants pay for these to enhance customer engagement and sales. This creates recurring revenue beyond transaction fees.

Funds held in WeChat Pay accounts before settlement to merchants can be invested to earn interest. This float income is significant due to the large volume of transactions. It represents a substantial revenue source for Tencent.
