This is NOT a consequence of chip card. In India, everything is chip and pin. Our ATM machines just need you to put the card in , chip side facing up and then take it out 2 seconds later (it glows green). Then you can put in your PIN number and move forward.
- icebraining 10y agoI think that's because ATMs are trusted devices, and only need a generic signed authorization to do anything. Payment terminals need to have the specific transaction amounts signed by the card, IIRC. At least that's the model I've learned here in my (European) country.
- sandGorgon 10y agoNo. ATM need to sign amounts as well,but keep the key in memory. I don't think it's a consequence of swipe vs chip or anything. It just the UX built into the machine. IMHO , consumers find it reassuring that they are asked for a pin AFTER the amount is entered into a swipe machine in a bar (where you are much more likely to be drunk). This kind of a mechanism is very nice when amount is entered by someone else (the retailer/cashier). At the ATM, you are the only one that enters the amount. So the pin entry at the end of the workflow is not a bug..It's a feature.
