10 CONTENTS What is NFC? (skipped for this audience!) NFC Tags Peer to Peer Card Emulation Virtual Target (Host Card) Emulation Reading Contactless Cards APIs & Built-in Apps Support

11 About NFC Tags Memory Cards that store data App takes action in response to the message Have a contactless interface Read by a device termed the Reader

12 About NFC Tags 4 standard NFC Forum tag types Various tag capacities Message format is standard (NDEF) Custom types ( external ) allowed Standard message types include Smart Poster, Text, URI

13 About Tag Circuitry

14 Field Detection and Power

15 Demo 1 NFC Business Card Front Back No coding or client app necessary Uses standard URL message format Leverages browser to take user to my ebusiness Card site Backend server code helps me track who I met, who downloaded my vcard, etc. w/qr Code For ios users w/nfc Tag For real smartphone users

16 Demo 1 NFC Business Card After scanning tag, developers can: Add my vcard to their address book which includes usual stuff plus: LinkedIn URL, Twitter handle, Slide Share link, BlackBerry Dev Blog link, My Blogger link, etc. Request a device, Register as a vendor, and visit BlackBerry dev site

17 Demo 2 NFC Fun Run Start timer Run! Stop timer Have a nice cup of tea

18 Register with Invocation Framework <invoke-target id="com.example.nfcracetime"> <type>application</type> <filter> <action>bb.action.open</action> <mime-type>application/vnd.rim.nfc.ndef</mime-type> <property var= uris value= ndef://4/my.rim.com/myrecordtype /> </filter> </invoke-target>

19 Client action C++ and Qt bb::system::invokemanager* _invokemanager = new bb::system::invokemanager(); void App::receivedInvokeRequest( const bb::system::invokerequest& request) { QByteArray data = request.data(); QtMobilitySubset::QNdefMessage ndefmessage = QtMobilitySubset::QNdefMessage::fromByteArray(data); } handlendefrequest(ndefmessage);

21 What is Peer to Peer NFC? Transfer data from one device to another Share information just by touching Any kind of data Photos, music files, address book contacts are typical examples For larger items let NFC negotiate a Bluetooth connection No need for the usual BT pairing process Simple!

22 What is Peer to Peer NFC? Select object to share Touch devices! NFC ( and maybe Bluetooth) Magic Bask in the admiration!

23 Share from QML InvokeActionItem { id: sharedndefdata query { mimetype: "application/vnd.rim.nfc.ndef" invokeactionid: "bb.action.share" } } onshowing: { // make NDEF message as byte array in C++ sharedndefdata.data = _ndeffactory.getndefvcardmessage(sendvcard.ndeffirstname, sendvcard.ndeflastname, sendvcard.ndefaddress, sendvcard.ndefemail, sendvcard.ndefmobile); }

24 Share from C++ NfcShareManager *_nfcsharemanager = new NfcShareManager();... void NfcSharing::fileShareContentChanged(QString paths) { NfcShareFilesContent request; QList<QUrl> urls;... // Construct a list of local file URLs from file paths... request.setfileurls(urls); // share mode File means Bluetooth connection handover _nfcsharemanager->setsharemode(bb::system::nfcsharemode::file); NfcShareSetContentError::Type rc = _nfcsharemanager->setsharecontent(request); }

31 Card Emulation In Use Touch handset to a reader Reader communicates directly with SE Optionally be notified of transaction Admire your purchase

32 Interact with Secure Element... rc = nfc_se_session_open_logical_channel(hsesession, the_aid, sizeof(the_aid), fcpresponsetype, &sechannel, &openresponselen);... rc = nfc_se_channel_transmit_apdu( sechannel, the_apdu, apdu_size, &exchangeresponselen );... rc = nfc_se_channel_get_transmit_data(sechannel, result, &nreceiveapdubuffersize));...

33 Transaction Notification... <invoke-target id="com.example.nfctool.tl"> <entry-point>1</entry-point> <type>application</type> <filter> <action>bb.action.notify</action> <mime-type>application/vnd.bb.nfc_transaction</mime-type> <property var="uris value="aid://sim/6e.66.63.74.65.73.74.30.31/"/> </filter> </invoke-target>...

36 What is Virtual Target Emulation? Touch handset to a reader Reader communicates with BlackBerry 10 App Application completes transaction Smile at new allocation of loyalty points!

37 Fool that Reader! Virtual target emulation makes your smartphone seem just like an NFC tag or card The reader cannot tell them apart Of course you cannot set the UID of the emulated target that is not under your control

38 Emulating an NDEF Tag... nfc_ndef_record_t *ndefrecord = makecustomrecord(qstring("my.rim.com"), QString("myrecordtype"), tagdata); rc = nfc_create_ndef_message(&_emulatendefmessage); rc = nfc_add_ndef_record(_emulatendefmessage, ndefrecord); rc = nfc_start_ndef_tag_emulation(_emulatendefmessage);...

40 What is it? Read data from physical (plastic) contactless cards Right into your application Reduce manual data entry e.g., credit card number Make card usage tracking more convenient e.g., view card use history or balance on BlackBerry 10 smart phone

41 What can you do with it? 1. Card details required 2. User presents contactless card 3. App reads details from card and completes form

42 How do you do this? Exactly *how* depends on the card type A credit card is not the same as an ID card Transit cards are not all the same Exchange APDUs with the card Response APDUs will contain the data you want You have to send the right command APDUs though Touch card to BlackBerry to fill in form Details for credit cards are defined in the EMV specifications

43 How do you do this? Touch handset to a card BlackBerry 10 App acts as reader APDU conversation with card yields data User delighted with result of your thoughtful feature

44 Code Example... rc = nfc_register_tag_readerwriter(tag_type_iso_14443_4);... nfc_tag_transceive(target, TAG_TYPE_ISO_14443_4, the_apdu, apdu_size, response, MAX_RESPONSE_SIZE, &rlength);...

45 Amsterdam Travel Pass Touch handset to Transit Card BlackBerry 10 App acts as reader APDU conversation with Transit Card Review your last two transactions
