Well, with centralised IT systems, it doesn't need to be a physical sticker on your passport but rather an authorization number associated with your passport number (more secure than relying on someone not faking the sticker). But the vetting process is still there. Fundamentally isn't it the exact same thing (a sort of an electronic helmet)?

You asked for a definition, so I looked it up. I'm not advocating a specific opinion.
