What feature is located on the back of a California driver's license?

The back of a California driver's license features a magnetic strip, which stores essential information about the license holder. This strip can be scanned by various devices, allowing for quick access to the driver's information by law enforcement and other authorized entities. It enhances security and facilitates the verification process without needing to physically inspect the front of the license.

The presence of a magnetic strip is especially important for ensuring that the data is transferred securely, and it can also assist in preventing fraud. Other features like a barcode or QR code, while possibly present in different forms of identification, are not standardized for California driver's licenses in the way that the magnetic strip is. The hologram typically serves as a security feature on the front of the license but is not a feature that appears on the back.
