Bridge/connector extension enabling digital signing of Vietnamese e-invoices using USB token digital certificates via native messaging

Vietnamese businesses need to digitally sign electronic invoices using hardware USB tokens, but web browsers cannot directly access USB token hardware. This extension bridges the gap between e-invoice web applications and a local native messaging component (com.tsd.einvoice) that interfaces with the USB token.

User installs the extension and a native messaging host component. When using an e-invoice web application (e.g., einvoice.com.vn), the web page sends signing requests via postMessage to the content script, which forwards them to the background script. The background script communicates with the native host (com.tsd.einvoice) which interfaces with the USB token to perform digital signing, and the signed result is returned back to the web application.

Target users: Vietnamese businesses using electronic invoicing / Accountants and finance staff signing e-invoices / Users of Thaison Technology e-invoice platforms / Employees at companies like Honda Vietnam, Coca-Cola Vietnam, and other enterprises listed in externally_connectable

Cannot inspect the native messaging host component (com.tsd.einvoice) which handles actual USB token interaction
Cannot confirm the full list of destination service features or their pricing models
The content script whitelist only includes einvoice.com.vn and einvoice.vn but externally_connectable has more domains - unclear if all are actively used

Monetization

No paid features detected

The extension contains no payment-related code, no premium feature gating, no subscription logic, no billing API calls, and no upgrade prompts. It is a free utility bridge that connects e-invoice web apps to a native USB token signing component. The keyword hits for 'pro' are false positives from Promise constructors, comments about 'probing', and base64-encoded metadata.

Confidence: 90
Payment platform: --
Source: AI / High
Login required: No
Reason: The extension is a pure bridge/connector between Vietnamese e-invoice web applications and a native messaging host for USB token signing. It contains no login UI, no authentication logic, no credential storage, and no session management beyond a simple sessionStorage flag marking the extension as installed. While the destination e-invoice services (einvoice.com.vn, etc.) likely require their own accounts, the extension itself does not gate any functionality behind login.
