Not all the models of Android and versions of the iPhone have NFC. However, all the versions of the iPhone, from the iPhone 6 and up to date have NFC chips in their hardware. In the case of Androids, most of the mid to high-end models of smartphones are made compatible with NFC. But, that doesn’t mean every phone has it. If you are specifically looking for an NFC integrated smartphone, it is best to talk to the manufacturer or the sales representatives before you make a purchase.
