On August 14, Apple suddenly announced that it would open up the iPhone's NFC chip to developers and allow them to use the phone's internal security components to launch contactless data exchange functions in their own apps. Simply put, in the future, iPhone users will be able to use their phones to achieve functions such as car keys, community access control, and smart door locks, just like Android users. This also means that the "exclusive" advantages of Apple Pay and Apple Wallet will gradually disappear. Although, Apple as early as 2014 on the iPhone 6 series, added NFC function. But only Apple Pay and Apple Wallet, and not fully open NFC. In this regard, Apple is really behind Android, after all, Android has long been rich in NFC functions, such as using mobile phones to achieve car keys, community access control, open smart door locks and other functions. Apple announced that starting with iOS 18.1, developers will be able to offer NFC contactless data exchange in their own iPhone apps using the Security Element (SE) inside the iPhone, separate from Apple Pay and Apple Wallet. With the new NFC and SE apis, developers will be able to provide contactless data exchange within the App, which can be used for closed-loop transit, corporate ID, student ID, home keys, hotel keys, merchant points and rewards cards, even event tickets, and in the future, identity documents.
