With iOS 11, NFC is for more than just using Apple Pay
With iOS 11 comes Core NFC. This allows developers to access NFC so that the tool can be used inside apps. With the latest build of Apple's mobile operating system, NFC tags can be read on certain iPhone models. This allows compatible devices to open certain apps, and change specific settings when it comes into contact with a tag. In addition, consumers can stand next to store shelves and learn more information about some of the products that s store is offering for sale. NFC can also help manufacturers track a product from a factory based assembly line, to its delivery inside a store.
Core NFC will be available for use on the Apple iPhone 7, Apple iPhone 7 Plus and later models. Interested developers can learn more about Core NFC by reading Apple's documentation. Simply click on the sourcelink.
