In the words of Neil Postman "What problem is this technology trying to solve??"

I just don't get it. How much easier do you need it to be than to hand someone an ID card?

The trade offs being made here for the ever slightest convenience make absolute no sense to me.

It is this weird technological addiction to novelty even when there is basically no value or even difference. The only gain is that it is new and novel.

It's not just convenience -- it's also about privacy. For example, I don't like disclosing my home address just to prove I'm old enough to buy alcohol.

With this, I won't have to since it allows for asserting proof of age without disclosing additional information.
