 Demo React Native application using `@icedevml/react-native-host-card-emulation` in order to emulate NFC Forum Type 4 Tag with an example URL NDEF.
 
+The emulated NDEF tag is recognized out of the box when it's scanned by another iOS/Android smartphone from the home screen's level (i.e. using background tag reading). This emulation is cross-compatible, the iOS could emulate a tag that will be recognized by Android and vice versa.
