About NFC Tags
Memory Cards that
store data
Have a contactless interface
Read by a device termed “the Reader”
App takes action in response to the message
12 22 March 2014
About NFC Tags
4 standard NFC Forum tag types
Message format is standard (NDEF)
Standard message types include Smart
Poster, Text, URI
Custom types (“external”) allowed
Various tag capacities

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 Code For iOS users
w/NFC Tag For real smartphone users
16 22 March 2014
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 examples
For larger items let NFC negotiate a Bluetooth connection
• No need for the usual BT pairing process
• Simple!

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

Processor, OS, file system
Can run special apps called
‘applets’
Secure Embedded in a

What is Virtual Target Emulation?
Smile at new allocation of loyalty points!
Application completes transaction
Reader communicates with BlackBerry 10 App
Touch handset to a reader
37 22 March 2014
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

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 22 March 2014
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 22 March 2014
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 22 March 2014
How do you do this?

feature
