Final answer:
Driver license/ID cards have a bar code system that stores specific data and machine-readable technology in compliance with the Real ID Act of 2005, which enhances security and facilitates identity verification.
Step-by-step explanation:
The driver license/ID card is equipped with a bar code system that houses various types of data essential for security and identification purposes. As per the Real ID Act of 2005, which aims to enhance homeland security, the bar code on these identification documents contains standardized anti-fraud security features, specific data, and machine-readable technology. This allows for easier verification of identity and authenticity of the document when being used for official purposes such as boarding commercial airlines or voting. The introduction of the Real ID has required states to invest significantly in reissuing and redesigning driver's licenses and identification cards to ensure they meet federal standards. As a consequence, this has streamlined processes for authorities to verify identities but also raised concerns regarding the tracking and monitoring of individuals' movements.
