droidcon 2012: What's the Hack is NFC .., Hauke Meyn, NXP


Published on

NFC, the intuitive contactless technology is finding its way into more and more mobile phone devices. NFC stands for Near Field Communication and is a contactless technology gearing to massively ease information gathering and content sharing. It's very easy to use and allows short range, point to point communication between NFC enabled devices as well as access to content on passive tags and cards. The presentation will focus to provide a technology introduction, some hints on already available applications with a life demonstration of the technology. We will discuss the use cases driving the technology, the level of NFC integration in Android. The NCF API and it's classes will be presented and last but not least we plan to run a little life coding session to show how easy applications can be enabled and can benefit from NFC.

  4. 4. NFC Devices use a combination oftechnologies Tag/Card Reader/Writer (Terminal)3 communication modes Multi-standard (ISO/IEC14443, JIS X 6319-4/Felica, ISO/IEC15693)Connect the world of appswith the physical world:Apps jump into the world and touchpeople, objects and other apps. P2P Communication (Device to Device)Connect devices through NFCIP-1, NFCIP-2 (ISO/IEC18092, ISO/IEC21481)physical proximity:A magical connection of devices bysimply touching them. A true device“hand shake”.Interactive wallet: Card Emulation (Secure Element)Incorporates the use of a secure element EMVCo (ISO/IEC14443)to allow your phone to act like an “interactivecard” for payment, transportation, ID andphysical access 4
  5. 5. Who defines how NFC gets integrated?The NFC Forum The mission of the NFC Forum is to advance the use of NFC technology by: – Developing standards-based specifications that ensure interoperability among devices and services – Encouraging the development of products using NFC Forum specifications – Educating the market globally about NFC technology – Ensuring that products claiming NFC capabilities comply with NFC Forum specifications – Promoting the NFC Forum N-Mark 5 5
  6. 6. The Mobile Revolution Ubiquitous Mass Shift to contactless >1B Smart Phones contactless infrastructure touch (payment, points transport, ID, consumer, tags) • Mobile banking/payments • Social networks • Appstores Smart Phone > desktop shipments; will exceed desktop + laptop shipments in 2012 Mobile Internet fastest growth in CE history, driven by Smart Phones Strong traction for NFC enabled handsets (OEM’s and MNO’s) Secure online/offline mobile transactions enabled by Secure Element (tamper resistant hardware) Fast growing payment, coupon, social network and location based marketing initiatives Convergence of traditional transit, access, and card experiences onto interactive devices Allows convenient, intuitive, secure means to take the online experience into the offline world 6
