Verification Items
Device Verification consists of 3 verification items. Each item analyzes device information to determine whether the device is a mobile device, and marks it as FAIL if determined to be a non-mobile device.| Verification Item | Target | Description |
|---|---|---|
| Browser check | User-Agent | Analyzes the browser’s UserAgent value and blocks the request if the accessing device is identified as a desktop PC or automation tool (bot). |
| Graphics check | WebGL Renderer | Detects the device’s GPU/graphics card through WebGL information and blocks the request if a desktop-only GPU or virtual environment is detected. |
| Screen check | Touch Points | Analyzes the device’s touchscreen support and blocks the request if the multitouch level falls below what is supported by mobile devices. |
Detection criteria are continuously updated, and specific detection logic is not disclosed for security reasons.
