The feature that can be found on the back of a California driver's license is indeed a magnetic strip. This magnetic strip is utilized for various purposes including encoding essential information about the driver, which can be quickly accessed and read by compatible machines or card readers. It enhances the utility of the driver's license as a form of identification and as a document that can be used in transactions involving age verification, such as purchasing alcohol or tobacco products.

While other features may be present on driver's licenses from different states or variations of IDs, the magnetic strip specifically serves a functional role in California's driver's licenses, storing data securely and allowing for quick verification processes. The inclusion of various technologies like QR codes or barcodes, while common in other contexts, often focuses on digital information access rather than the traditional data storage methods represented by the magnetic strip.
