Hardware bridge/SDK extension enabling web applications to capture electronic signatures from Topaz signature pads and GemView tablets via native messaging

Web applications cannot directly communicate with USB signature pad hardware. This extension provides a bridge between JavaScript in web pages and Topaz signature pad hardware through Chrome's native messaging API.

1) Developer includes SigPlusExtLiteWrapper.js in their web app. 2) Content script (SigPlusExtLiteSigningChromeExt.js) injects into all pages and sets up DOM attributes for extension detection. 3) Web app calls Topaz SDK methods (e.g., Connect, SignatureCapture). 4) Content script relays commands to background service worker (SigPlusExtLiteBgExtn.js). 5) Background script communicates with native SigPlusExtLite host application via chrome.runtime.connectNative(). 6) Native app interfaces with Topaz hardware. 7) Response data (signature image, raw data) flows back through the same chain to the web app.

Target users: Web developers integrating Topaz signature pads into web applications / Enterprise/business users using Topaz electronic signature pads / Integrators building document signing workflows with Topaz hardware

No external API calls detected — extension is purely a local hardware bridge, so remote service analysis is not applicable
Native messaging host application (com.topaz.sigplusextlite.win.2) is not included in the extension package — it must be installed separately by the user

Monetization

No paid features detected

No references to premium, subscription, payment, license, upgrade, or billing exist in the source code. All 'pro' keyword matches were false positives from JavaScript's hasOwnProperty() method calls. The extension is a free developer SDK/bridge for Topaz hardware. Users must purchase Topaz signature pads/tablets separately as physical hardware, but the extension itself has no monetization or feature gating.

Confidence: 98
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension contains no login UI, no authentication flow, no account creation, and no references to login, credentials, or authentication in its source code. All 'signin' keyword matches were false positives matching 'signing' (signature capture), not 'sign-in'. The 'session' matches were sessionStorage for screen position detection. The extension operates purely as a local hardware bridge between web pages and Topaz signature pads via native messaging.
