Which form of identification is generally considered unacceptable for verifying someone's identity?

Digital identification on a mobile device is generally considered unacceptable for verifying someone's identity in many security contexts. This is primarily due to concerns about authenticity, security, and the potential for manipulation. Unlike physical forms of identification that are issued by authoritative bodies, digital IDs can often be altered or forged more easily. They may lack the necessary security features that ensure their validity, such as watermarks, holograms, or other physical indicators present on traditional IDs.

On the other hand, state-issued photo IDs, employee identification cards, and passports are all tangible forms of identification that are recognized for their reliability and security features. They are typically hard to replicate and have undergone a verification process by a governing authority, making them more trustworthy for confirming someone's identity in various situations.
