<p>If you want to emulate an NFC card that is using these protocols in your app, create a service component based on the {@link android.nfc.cardemulation.HostApduService} class. Whereas if your app instead uses a secure element for card emulation, you need to create a service based on the {@link android.nfc.cardemulation.OffHostApduService} class, which will not directly be involved in the transactions but is necessary to register the AIDs that should be handled by the secure element.</p>
