Why would you have to stamp a visa? Most visa I get are digital. Once again, the US being an exception. I've never had the facial recognition fail on me, although it does happen that I need to take off my glasses. True, I don't travel to Middle-America that often. I'm mostly in Europe, North-America and Asia. Except for the US, I barely have any other stamps. Most simply work by registering my passport number. What I'm saying is: It already exists. I assume you have a US passport, which may work differently given that US border control still looks at the paper version. But in most countries, nobody ever looks at my paper passport. Everything happens with that chip inside of it. I could cut out the chip and still enter most countries just fine. And yes, sometimes I do need to get a visa. Which is registered on my passport number and probably some extra details like nationality. All those details are also in the chip, cryptographically signed by my government.

I'm not sure why you think the info in the article is false. Digital passports have existed for a while now. EU passports have had a chip in them for over 10 years, which is read and used by most automatic passport gates all around the world. There is in fact an open standard supporting this. I travel a lot, with my EU passport. I had a few trips recently where I flew into Canada, then continued to the US and back to the EU. When I flew into Canada, my passport was automatically read, face compared and I was allowed entry. Very easy. The only time people actually cared about the paper passport is when I entered the US. US Border control tends to still look at the paper version. Which, internationally, is uncommon in my opinion.
