Now it's a fiddle with an app, then try to get the right angle on a smudgy reader. Getting onboard takes much longer and it feels like technology sent us 2 steps back instead of forward.
IC cards are better, and if they could be integrated in the phone then it would be even better and faster for everyone.
I think most QR systems include some sort of rolling timestamp to combat that.
Forcing use of an app and QR codes does seem like a significant step back, although I guess it makes paper tickets much easier to implement with the same scanner.
Well, a number of smaller transport companies are turning away from IC cards citing the cost of the equipment. I don't know at which point in the stack the greed is coming in - whether it's the IC committees, Sony with the underlying technology, some other player or all of them at once - but it's happening. JR East can probably sustain Suica for decades but you'll notice they've been making a hard push into traditional credit cards and banking; they've seen which way the wind is blowing.
