I checked the Whitepaper (mostly useless), the Sony developer website, googled the net, etc. but couldn't find the information.
I need to know what NFC chip is used in the Z3+. Based on what chip is used in older Sony phones (Z, Z2, etc.) it should be a chip from NXP and most likely it's a PN65N bundle (which combines a NFC chip with a secure element).
First of all, no places I go actually take the chip, they all still do manual swipe.
Secondly, I read somewhere that cards in the US are only chip, not chip and PIN. And that having chip only does not provide and additional fraud protection. The new chip cards I have gotten in the mail do not come with a PIN number. So what is the deal?
