> I still use at least one non-chip/magstripe-only card regularly… Well, one day!
I’m 2018 I went to visit my family in Australia. Only one of my US cards had a chip but I called and got a different card to send me a chip version so I’d have two.
Got home, tried to buy a coffee and the bloke behind the counter called out to a colleague “hey, do we still have a way to pay with a chip?”
(Of course most places did, but it was on its way out)

Interesting, because everybody uses contactless there?
I wonder how well (or if) that works with European-issued cards – some issuers require these to be inserted and a PIN be entered every few payments to reset the internal risk counters.
This isn't necessarily evidence of local computation though – the EMV protocol is fairly lightweight (even for 90s standards), and I could imagine a remote EMV terminal implementation, with the handful of ISO 7816 APDU exchanges required for a minimal payment being sent over the network.
That's how e.g. the Nintendo 3DS can support Suica payments, which is another amazing (and to me unexpected) application of a normally merchant/terminal-side payments technology in consumer hardware.
