Contactless payments are becoming more widespread in the US. At this point, the only store that I frequent that doesn’t accept contactless payment is Home Depot. I recently went on a week long road trip and 90+% of my transactions were contactless.

They are widespread in the US too. Yes, we were slower to adopt them than others, but for the last few years we have had them.

It's very recent, wich is the point of my post, we lost so much time with meaningless things

Contactless payments was already adopted in Canada for several years by 2010 [1]. It’s not recent. Not sure why US is slow in this adoption though

Come on, it was just for a very small minority, and you couldn't do it for every payments, most businesses refused for small payments because of the fees, "CC only after X dollar" kind of rules

And you still can't use your phone, a joke this system is

But again, outside of the US it isn't. Contactless payments have been common in Europe and had widespread usage for a decade. Chinese and European adoption was pretty similar.
