According to ID verification standards, which feature is NOT valid?

Artistic impressions are not a valid feature for ID verification standards because they do not consistently provide accurate or reliable information about the identity of the individual. Effective ID verification relies on features that can be objectively verified and are difficult to reproduce or alter, ensuring that a document is authentic.

In contrast, micro prints, security backgrounds, and raised prints are all legitimate security features used in identification documents. Micro prints are tiny text or images that are often difficult to see without magnification, making them hard to counterfeit. Security backgrounds involve intricate designs and patterns that are embedded in the ID to prevent duplication, while raised prints create a tactile feature that can be felt, adding another level of verification that can be sensed by touch. These features serve to enhance the security and credibility of identification documents, making them essential components of effective ID verification standards.
