Qrow is a project mainly written in Java, it's free.
QROW - QRs that live in WIFIs. Discover QR Over Wifi.
QROW is a system that intends to discover QR over WIFI. The idea is to find places in which "QROWs" fly. You open your mobile app, and catch those QROWs.
The idea is to make it as simple as QR codes are. You find a QROW, and it takes you where it is supposed to take you.
The same idea here: you find a QROW that remains in a WIFI, and it takes you to whatever service, page, ... lives inside that WIFI.
QROWs are multicasted from a QROWServer. QROWReceivers just catch QROWs and shows them to the user. The user selects the QROW who wants to read.
QROWs can be used as a very SIMPLE system for services and pages discovery in a local zone.
