NFC Forum Technology Architecture
How Does an NFC Mobile Device Work?
Connecting apps with the physical
world:
Apps jump into the world and touch
people, objects and other apps.
Connect devices through physical
proximity:
Easily connect devices simply by
touching them. A true device “hand
shake”
Interactive wallet:
Incorporates the use of a secure
element to allow your phone to act like a
card for payment, Transportation and
physical access

How Does an NFC Tag Work?
• Same fundamental principle as RFID, contactless smart cards or access
control badges
• Reader (e.g. mobile device) provides power, initiates RF communications
& captures data from the tag (or programs data into the tag)
13.56MHz
What Is an NFC Tag?
• An NFC tag is a contactless tag capable of storing NDEF
formatted data, which interoperates with ISO14443
infrastructure and NFC devices as defined by the NFC
Forum
• An NFC Forum tag is compatible to one of four NFC
Forum Tag platforms capable of storing NDEF
formatted data
• ICODE, MIFARE Classic can be NFC tags, but NOT NFC
Forum tags
• MIFARE Ultralight, UltralightC, MIFARE DESFire and
SmartMX can be NFC Forum tags
NFC Forum Type Tags
• NFC Forum Tag is a contactless tag compatible to one of four NFC Forum Tag
platforms capable to store NDEF formatted data
• NFC Forum introduced standardized technology architecture, initial
specifications and tag formats for NFC compliant devices in June 2006
• These specifications include:
 NFC Forum Data Exchange Format (NDEF), defines a message encapsulation
format to exchange information
 Record Type Definition (RTDs) The RTD specification provides a way to
efficiently define record formats for new applications and gives users the
opportunity to create their own applications based on NFC Forum
specifications of TEXT, URI, Smart Poster, and Generic Control.
What the NFC Forum Has to Do with It: Reader/Writer

What Is NDEF?
• A contactless device capable of
storing NFC Data Exchange Format
(NDEF) data to operate NFC devices in
accordance with the NFC Forum in an
ISO-14443 infrastructure
• An NFC Forum tag is compatible with
one of four NFC Forum Tag platforms
capable of storing NDEF formatted
data
• NDEF defines a message
encapsulation format to exchange
information
What Is RTD?
• Record Type Definition (RTD)
provides a way to efficiently define
record formats for new
applications and gives users the
opportunity to create their own
applications based on NFC Forum
specifications of TEXT, URI, Smart
Poster, and Signature
• Enables secure architectures,
strong enough for payment and
secure access applications
