Yes, you can use the "Yitongxing" (亿通行) APP. To register, you need a Chinese mobile number or bind your passport via the international version (if available). Payment can be made indirectly by linking international credit cards to WeChat Pay or Alipay. Steps: Download the app → register/complete real-name authentication → select a payment method → generate a travel QR code, then scan it to enter/exit subway stations. The app is primarily in Chinese, so prepare translation tools in advance.
