We are just stuck in our ways over here. We just got tap payments a few years ago. Even then some vendors still don’t support tap to pay lol.
I always wondered why the US seems to be a hold out for adopting new technology. It might just because out government is extra slow at getting anything accomplished.
For SMS I wondered if it has something do with communicating between countries. In your experience was their extra charges involved with sending a SMS to someone in another country. (Back in the day when SMS was popular)
Here in the US we can SMS to anyone within the US for no extra charge. And we mostly talk amongst ourselves over here. So cost wise it isn’t an issues. If I was talking to people outside the US there is no way I would use SMS.
I have been hosting random public services for years publicly and it hasn’t been an issue.
Edit, I might have miss understood the definition of public. I have hosted stuff publicly, however everything was protected by a login screen. So it wasn’t something a random person could make use of.
