I'll note that Web-browsers can get access to the camera phone and scan QR Codes: https://github.com/schmich/instascan and Web Bluetooth is released in many of the latest/popular browsers: https://caniuse.com/#feat=web-bluetooth ... and WebNFC just went into Origin trials in Chrome: https://developers.chrome.com/origintrials/#/view_trial/236438980436951041 There continues to be confusion around the colloquial use of the word "Web", which among developers, is mired in the historical protocol that spawned the Web -- HTTP. The colloquial use is often outdated and wrong. The W3C is about the "Web Platform", which is not limited to HTTP. Wikipedia has a decent definition here: https://en.wikipedia.org/wiki/Web_platform ... but here are the other protocols that are not HTTP that are viewed as being part of the Web platform: * TLS * Geolocation (and by extension, the Global Positioning System, protocols and data formats) * Web Sockets (which are not HTTP!) * Web Of Things (IoT, CoAP, etc.) * WebRTC (and a whole bunch of IETF specs on signalling and media encoding/transmission protocols) * Web Bluetooth (Bluetooth and its data formats and protocols) * NFC (again, data formats and protocols) * Media Capture API (audio and video formats and protocols) The W3C is not solely about HTTP, and you learn that pretty quickly when you go to a W3C Technical Plenary, or participate in various standards groups at W3C. I understand that it's difficult for many to participate in that way. Fundamentally, the Web Platform is a bridging technology, connecting all of these disparate data formats and protocols into a cohesive application development environment. So communication of Verifiable Credentials over NFC, Bluetooth, WebRTC, Web Sockets, QR Codes... IMHO, all very much in scope. -- manu -- Manu Sporny - https://www.linkedin.com/in/manusporny/ Founder/CEO - Digital Bazaar, Inc. blog: Veres One Decentralized Identifier Blockchain Launches https://tinyurl.com/veres-one-launches
