If your computer is asking for a driver for this specific CID, it usually means the card you inserted requires a . DriverIdentifierhttps://www.driveridentifier.com
Smart cards used for corporate networks, government ID, or banking usually require standalone middleware.
According to driver catalog repositories like DriverIdentifier , this particular GUID string is widely paired with generic smart card systems deployed across custom motherboard configurations, such as OEM builds by manufacturers like Gigabyte. Why Does It Show an Error in Device Manager?
Because SCFilter operates at the kernel level and intercepts file‑system and device I/O, it occupies the same space as modern and antivirus minifilter drivers. A Windows file‑system minifilter is a specialised driver designed to intercept and modify I/O requests sent to a file system or another filter driver, and such drivers are used by a wide range of security software.

Technical Deep Paper: Architecture and Discovery of SCFILTER Card Identifiers 1. Introduction to SCFILTER
(Content ID or Campaign ID) is a technical parameter used to track or trigger specific Augmented Reality (AR) Lenses geofilters advertising campaigns within the Snapchat app. 🔍 Technical Breakdown
While SCFILTER itself is a legitimate Microsoft driver, scammers and malware authors sometimes use smart card identifiers to hide malicious activity. The domain safenull.org , which was scanned by urlscan.io on May 27, 2026, was flagged as suspicious. Its IP address (188.114.97.3) belongs to Cloudflare, and the site is hosted on a 2‑year‑old TLS certificate. Users are advised to exercise caution and never download drivers or software from untrusted sources claiming to be associated with smart card CIDs.
This dynamic behavior is not a bug—it is a fundamental feature of how Windows identifies individual smart cards. The CID ensures that each card is treated as a unique device, enabling per-card driver and credential management.
: The physical USB or integrated smart card reader is fully functional and has proper system drivers.
If you are encountering the flaky 099-scfilter test in Debian’s chrony package, note that this issue has been reported as a Debian bug (Bug#1111222) and was fixed in version chrony/4.7-3 . Upgrading to the latest version should resolve the intermittent test failures.

Use the tracelog command with the appropriate GUID:
Are you seeing this ID in a or as part of a malware scan report?
In Windows, when you insert a smart card (like a security token, employee ID, or cryptographic card) into a reader, the system needs to identify what kind of card it is to load the correct driver.
