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

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
