DSC Token Not Detected?

A DSC token is a secure USB device that stores your Digital Signature Certificate and enables you to sign documents electronically. When you connect the token to your computer and initiate a signing process, Chrome communicates with the token through the required drivers and signer utility to access the certificate.

However, if Chrome is unable to recognize or communicate with the token, you may encounter the "Token Not Detected" error. As a result, the certificate stored in the token cannot be accessed, preventing you from completing the signing process.

Common Reasons Behind the "USB Token Not Detected" Error

Here are the most common reasons behind the “DSC Certificate Not Showing in Chrome” error:

1. USB Token Connection Issues

A loose connection, faulty USB port, or improperly inserted token can prevent your system from recognizing the device.

2. Missing or Outdated Token Drivers

DSC tokens require specific drivers to communicate with your computer. If these drivers are not installed correctly or have become outdated, Chrome may fail to detect the token.

3. Signer Utility Problems

Most DSC-enabled portals rely on a signer utility to establish communication between the browser and the token. If the utility is not installed, not running, or not updated, the token may not be detected.

4. Browser Compatibility Issues

An outdated version of Chrome or incorrect browser settings can sometimes interfere with the token detection process.

5. Disabled or Missing Browser Extensions

Some websites require dedicated extensions for digital signing. If these extensions are disabled or missing, Chrome may not be able to access the DSC token.

6. Antivirus or Firewall Restrictions

Security software can occasionally block the connection between the token, signer utility, and browser, resulting in detection errors.

7. Hardware-Related Issues

A damaged USB token, faulty USB port, or system hardware issue can also prevent successful token recognition.

8. Operating System Conflicts

Pending system updates or compatibility issues between the operating system and token software may affect the token's functionality.
