Over the years, the evolution of ID documents has been remarkable. For instance, the original driver's license issued in the US did not have a photo. However, as identity fraud became more prevalent, state governments began to add photos to driver's licenses as a way to verify identity. Recently, the Real ID Act was passed in the US, which requires a stricter set of standards for state-issued IDs, including more secure features and identity verification processes. Outside the US, many countries have national ID cards that are used as a primary form of identification. For example, India's Aadhaar card is a biometric-based national ID system that has been in use since 2009, and it currently covers over 99% of the country's adult population. Similarly, Brazil has introduced a Mobile ID program that allows citizens to use their mobile phones as a form of identification, which is particularly useful for those who don't have traditional forms of ID. As ID documents have evolved, so too have the challenges associated with verifying them. With the increasing prevalence of digital IDs, biometric data, and new sources of personal data, the process of identity verification has become more complex and nuanced.
