Can I use my phone to scan an ID?

I'm curious, can I actually use my phone to scan an ID? It seems like such a convenient way to handle identification verification, but I'm not sure if it's actually feasible or if there are any security concerns I should be aware of. Is this a technology that's widely used and accepted, or is it still in its infancy? Are there any specific apps or software that you would recommend for scanning IDs on a smartphone? I'd love to learn more about this process and how it could potentially benefit me.
