Yay for astroturfing RFID
There's no reason you couldn't go chip-no-pin. In fact, it was tried, and it flopped. The upshot of this re-try with added "look ma no touchy!" is that with a rogue terminal it's still good chances to rip lots of people off that merely walk by. I'm tempted to try just to prove the point.
And there's the problem of privacy, same as with chip&pin, or magstripe&pin, or take an impression of embossed numbers and sign, or any other system to date, really. Each transaction leaves a paper trail containing amount, retailer, you, date and time down to the second, and place. And it'll keep for years. And leaky paper trails are a good source of income for criminals too. Dumster diving for cc slips was good pickings before databases accessible over the internet full of cc numbers proved to be even more profitable.
Fix that privacy thing and come up with some real security instead of this make believe crap and I'll consider using an electronic system beyond getting cash from some cash dispenser then parcelling that out over a couple of weeks. Or maybe not. Cash I can count easily and, quite literally, keep my spending in hand. Electronic payments, not so much.
It's all about control, and YOU the consumer, aren't allowed to have it. Ha ha!
