QR Codes on the Big Screen
2 Oct I’ve been using QR codes in my classroom for scavenger hunts and as a tool for research. If you haven’t viewed my presentation on making your own QR codes and using them in the classroom, check it out here. If I want all of my students to visit one website (especially one with a combination of characters that might be hard to type in) I’ll project the QR code onto my board and have all students scan it straight from their seats. This eliminates the printing, copying and distributing of papers and makes for a quick, easy scan for all students. Try projecting this QR code and scanning it yourself!

Android Ideos and QR-Codes, practical limitations - The Nyaruka Blog
We're a huge fan of the Huawie Ideos phones. They are ridiculously cheap, $100 unlocked, and can be bought over the counter at Safaricom in Kenya or about $120 from NewEgg in the states. That is a crazy pricepoint, totally blowing away any other Android phone and really making J2ME handsets mostly irrelevant as contenders for the kind of ICT4D projects Nyaruka undertakes. Recently we've been working with a client and have been considering using these as a way of managing and tracking inventory. After all, the cheapest barcode scanners are around the same price, and you don't get a built in touch screen, GSM connectivity, GPS and the ability to build the entire application on the device. One thing we were curious about though is just how well they would perform with high resolution 2D barcodes. Methodology We created and printed 2D bar codes encoding 23, 50, 100, 200, 500 and 1000 characters, then tested them at different sizes. Camera Specs Scoring Results So what did we find? Full Results
QR Codes Scanning Distance | qrworld
The invisible bubble of space that constitutes each person territory plays a major role in our social life. In his book “The Hidden Dimension” Edward T. Hall elaborates on the distance factor role in animal social life and humans as well. It appears that people use the same distance rules when interacting with objects as well and QR codes are not an exception. Many times people mention that they were embarrassed to scan a QR code in certain circumstances, or needed to act strangely in order to scan a code. This is when the hidden distance factor enters into the play, a factor that we must be well aware of it if we want a good response for our QR codes. Meaningful distances for humans Four distances are mentioned in Hall book; - The intimate distance – effectively zero distance - The personal distance – this is the distance separating members in a no-contact state. QR codes are encountered in different circumstances, many of them fits into one of these distances. Distance and QR code size
