Demo 1 – NFC Business Card

• 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.

Front Back

w/QR CodeFor iOS users

w/NFC TagFor real smartphone users

1612 April 2023

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

Transfer data from one device to another• Share information just by touching

Any kind of data• Photos, music files, address book contacts are typical

examplesFor larger items let NFC negotiate a Bluetooth connection• No need for the usual BT pairing process• Simple!

What is Peer to Peer NFC?

What is Peer to Peer NFC?

Bask in the admiration!

NFC ( and maybe Bluetooth) Magic

Touch devices!

What is Virtual Target Emulation?

Application completes transaction

Reader communicates with BlackBerry 10 App

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

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);

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

4112 April 2023

What can you do with it?

1. Card details required

2. User presentscontactless card

3. App reads detailsfrom card and completes

form

4212 April 2023

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
