Something sad of Japan IMHO, is that the national IC system works that well that credit card acceptance has been delayed greatly (and the whole banking system is a joke but that's a topic for another day). For the last 5 years every time I go back to my home country I see wonderful innovations and steps forward, while today you still find many places that don't accept credit card at all in central Tokyo, let alone tap-to-pay. A good example on-topic is that I've heard that in London you can pay with your credit card straight away on the underground tickets, tap it and enter and then tap it to exit (and you get charged), no need to even buy tickets. Note: I'm comparing this to Europe, I've heard that Japan is amazing compared to the US so I guess CC and payment systems in EU should be even more amazing for the US readers over here?
