There is no guarantee that what's being put in phones today is going to be necessary or compatible with what ends up "winning" mobile payments. Notably last month a group of major retailers (walmart/target/711/sears/best buy...) announced they are going to push what sounds like a non-chip solution.
- mpclark 14y agoThe MCX solution doesn't yet sound like anything and I believe it is simply a gun that is being brought along in case there is a fight over merchant fees. There is a huge amount of work going on all over the world on putting NFC into place. It's not very visible yet, but it is happening. Notably, hardware is being quietly rolled out on both the user and merchant side. It's always possible something else might 'win' in the end, but I'd say it is increasingly unlikely...
- tomelders 14y agoHow do I pay for something with NFC when I'm actually on the phone? And how do I pay for something if I don't have my phone. Or if my phone is out of charge. Genuine questions by the way. If anything, it makes more sense to have NFC in a card. I'm not sure how convenient it is to have a method of payment that can run out of battery.
- 18pfsmt 14y agoNFC, as it was originally envisioned, was supposed to allow for use even when the phone was without power just as the cards today are without power. In traditional RFID technology, from which NFC was derived, there was a powered transceiver (aka reader) and non-powered transponder (aka card). The promise of NFC was to be able to have a transceiver and transponder in one, where the power is derived from the inductive coupling of the antennae. You can see this by reviewing the ISO documents for ISO 14443 (RFID) and ISO 18092/ 21481 (NFC).
