Many identification cards lack which type of security features?

Many identification cards may lack images that are visible only by UV light. This specific security feature is less common compared to others because incorporating such technology can be more complex and expensive. It is typically used in high-security environments where counterfeit prevention is a significant concern. As a result, many standard ID cards, especially those used for less sensitive applications, may opt for more basic security features rather than UV-visible images.

Barcodes, magnetic strips, and watermarks are widely employed in identification cards as they are cost-effective and facilitate various functionalities, such as data storage, scanning for verification, and providing a layer of visual authenticity. These features can be easily integrated into a wide range of IDs, making them more prevalent compared to UV-light images, which are less visible and require specialized equipment to view.
