  • Think of it as a Facebook for Things Where all things have unique identities, which are represented online. This is what we at EVRYTHNG call an Active Digital Identity This allows us to… Attach content to them  To communicate via them  To connect apps and services to themWhich enables things to be part of the real-time social flow of digital conversations which happens around us every day
  • The ``what'': what tagged products (EPCs) were read. The ``when'': at what time were the products read. The ``where'': where were the products read, in terms of Business Location (e.g. ``Floor B''). The ``who'': what readers (Read Point) recorded this trace. The ``which'': what was the business context (Business Step) recording the trace (e.g. ``Shipping'').Set of standards:Creating an « Internet of Things »The EPCIS is the information service:Sharing of RFID data.Exposes as standard WS-* interfaceServeral EPCIS vendors:SAP AII (Auto-Id Infrastructure)IBM InfoSphereFosstrak EPCIS (open source)Oracle Oracle Sensor Data Manager

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

  • Android, NFC, QR & EPCReady to Tag the World?Dominique Guinard, PhD.CTO @ EVRYTHNG Ltd. London / Zurich348 / J12.2
  • Your World is Being Tagged Today!
  • 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.
  • 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?)
  • 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.
  • 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/
  • 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]
  • 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
  • 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
  • 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
  • Useful Links• REST library for Android and EVRYTHNG API wrapper: • https://github.com/domguinard/ThngDroid/• FreezeMe sample app: • https://github.com/domguinard/FreezeMe• Nice NFC/Android tutorial: • http://netmagazine.com/tutorials/getting-started-nfc-android• Web of Things community blog: • http://www.webofthings.org• Web of Things Thesis: • http://www.webofthings.org/dom/phd/thesis.pdf• Fosstrak EPC open-source stack: • http://www.fosstrak.org• Jazoon presentation on EPCIS Web (REST) Adapter: • http://slideshare.net/misterdom/restifying-ws-services-case-study-in-rfid• Signup for EVRYTHNG account (for your next IoT / WoT projects): • http://evrythng.net 11

  • 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
  • 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
  • The EPC Network in a Nutshell
