The first blocks describe the initialization of the necessary layers and components

independent of the card emulation. After the layers have been initialized, the card

emulation can be initialized too. After applying the protocol settings, the PN512 waits for

a successful activation of the card side. This activation can be done for example by an

NFC enabled mobile device.

Now the reader on the opposite can read the NDEF message that is presented from the

PN512. If this message gets modified, for example by an Android mobile, the card

emulation application passes that message to the Java application that posts it on

Facebook.

As soon as the Java application is done, the NFC application again waits for the next

message.

7.7 Android Application

7.7.1 The Application

Basically, the application is meant for reading or writing of NDEF messages from either

an emulated card or an NFC Smart Card. On the main screen you can choose between

the two screens “Read” or “Write”. With the “Read” screen you can read NDEF

messages that have already been stored on the emulated card whereas the “Write”

screen enables you to browse the message store, create, delete and modify messages.

7.7.2 Installing the Application

Connect your phone with the computer (Micro USB). Now you can see your phone in the

Windows Explorer. Open the internal store.
