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 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
