- sliken 9y agoIt's not been uncommon for apple to limit new features to new phones, even without a hardware limitation.
- eridius 9y agoNo it's not. Features that are limited to new phones that don't need some dedicated hardware are typically done for performance reasons, which is still a hardware reason.
- gergles 9y agoNot that I can see. The NFC chip in the iPhone 6S is the NXP 66V10, and in the iPhone 6 it's the 65V10. These appear to just be different packages of the underlying PN544 part from NXP. It supports reading NDEF tags (as I imagine every commercially-sold NFC chipset does - they're called "NFC Forum tags" in the datasheet [1].) There was also no hardware reason to limit Suica support to the iPhone 7; this NFC controller supported FeliCa too. 1: http://www.nxp.com/documents/leaflet/75016890.pdf http://www.nxp.com/documents/leaflet/75016890.pdf
