Does the iPhone 7 / iPhone 7 Plus have NFC?

Yes, the iPhone 6 and iPhone 6 Plus were the first iPhone models to ship with NFC. However, the Near Field Communication in Apple products is currently only used for Apple Pay and not for reading NFC tags. There have been rumors that Apple may open SDK access to the NFC controller with the release of the iPhone 7, but it was not released in iOS 10, like some had predicted.
