NFC, QR, EPC and Android: Ready to Tag the World!

  1. 1. Android, NFC, QR & EPCReady to Tag the World?Dominique Guinard, PhD.CTO @ EVRYTHNG Ltd. London / Zurich348 / J12.2
  2. 2. Your World is Being Tagged Today!
  3. 3. EVRYTHNG: A Facebook for Things Think of a Facebook for things − individual things with unique digital profiles, like we have, to update, share and add to… Applications EVRYTHNG APIs & Services Tags Objects An Active Digital Identity profile for every thing.
  4. 4. Android • Mobile phones as bootloaders of the IoT • Android as the Tricorder: – Massive penetration world- wide! – Great QR support (open- source libs) – NFC support in the SDK (iPhone? Hello?)
  5. 5. Level 1: QR Codes • Golden rule: • QRs only you shall use! • Royality-free encoding algorithm (Toyota’s Denso Wave) • 40 different levels • 4 error correction levels • Add a logo! • Standardized content: URLs, v-card, etc.
  6. 6. Android Loves QRs! • Zxing open-source library: • Great scanning of 1D + 2D QR codes. • Supported on a very wide range of (Android) devices. • Embedded in your app or called via Intent. • code.google.com/p/zxing/
  7. 7. Level 2: NFC: Near Field Communication • 13.56 MHz, “Touch” technology • Driven by NFC Forum (Nokia, Intel, Visa, etc.) • NDEF: Data standard (URLs, Text, Poster, etc.) [Image courtesy of Timo Arnall www.elasticspaces.com]
  8. 8. Android Loves NFC! • Decent NFC support since 2.3.3 (API v10, Gingerbread) • Wake up applications on tag discovery (w/fiters) [http://www.mobiletor.com] • Relatively complex but powerful API • Nice tutorial: netmagazine.com/tutorials/ getting-started-nfc-android
  9. 9. Level 3: EPC: Electronic Product Code • 96 bits world-wide unique product identifier & standards • Commercial attribution of codes (GS1) • EPC can be written to NFC tags • EPC Gen2 tags enable distant reading (5x meters) • Fosstrak EPCIS Web Adapter for EPC to URL • EPC loves Java: • fosstrak.org 9
  10. 10. Java Loves EPC! • Java open-source implementation of EPC standards (Auto-ID Labs) • Modules: • Low-level reader protocol (LLRP) [http://www.fosstrak.org • Tag Data Translation (TDT) • EPC Information Service (EPCIS) • EPCIS Web Adapter (REST) • Etc. • slideshare.net/misterdom/restifying- ws-services-case-study-in-rfid

  13. 13. Level 3: EPC: Electronic Product Code • 96 bits world-wide unique product identifier & standards • Commercial attribution of codes (GS1) • EPC can be written to NFC tags • EPC Gen2 tags enable distant reading (~ 10th of meters) 13
  14. 14. Level 1: Barcodes 1D: No item identification 2D: (to) many standards! Some insanely proprietary! QR codes: > Supported by 99% of the readers > Good readability > Several levels
  15. 15. The EPC Network in a Nutshell
