| Success Rate | 30%-50%, highly unstable | 95%+, near-perfect for popular apps |
| Privacy Protection | Codes publicly visible, easily stolen | Codes visible only to account holder, HTTPS encrypted |
| Number Resources | Popular regions often unavailable, high duplication | 160+ countries, real-time quality monitoring |
