# ScannerBench

> A free browser tool for inspecting barcode-scanner input, comparing exact values and collecting a useful diagnostic report.

Canonical site: https://scannerbench.smartfact.ai/

Capture text from scanners that behave as a native keyboard. Inspect characters and browser key events, compare a known value, import shared test expectations and download a reviewed report. Enter, Tab, manual finish and opt-in idle completion are available.

This is a software-tested alpha. Physical scanner and OS combinations are not yet qualified. Model selection provides reviewed manual references; it does not detect, configure or certify a scanner. Raw HID, serial input, camera scanning, barcode decoding and GS1 interpretation are outside this release.

Scan values, expectations and device notes are processed in browser memory. No account, upload or tracking scripts are required. Reloading loses the session. Reports are redacted by default and downloaded only after review. Hosting may log ordinary page requests; suite links contain only a fixed referral marker.
