Now what about business cards?
As I learned in Hiroto Kobayashi’s new book “After GAFA: A Map of the Future of a Decentralized World”, one of the SDGs (Sustainable Development Goals) adopted by the United Nations is “By 2030, all Provide people with an identity that includes birth certificates”.

The widespread use of positive IDs will eliminate falsehoods and slander through anonymous postings, and it will also eliminate academic fraud by politicians. Internet elections that take advantage of this will also be more accurate.

… So, do you need a business card?
