QR-коды, или Коды быстрого реагирования, все ярость в наше время. Вы знаете,, эти черно-белый штрих-кода вида рюшечки, которые появляются на журналы, плакаты, и даже некоторые футболки.
QR Code самом деле очень похож на штрих-код: это образ, который кодирует данные подобно URL-адресов, телефоны, слова, и более. Вы можете даже сфотографировать и вроде превратить его в QR кода (Изображение загружены в Интернет и QR код кодирует URL изображения.) Конечно, вы потеряете немного эстетическую ценность, но эй.
Но, you ask, what’s the point of these QR codes if you just store data in them? To hide that embarrassing photo from the Christmas party? Good guess, but no.
Most smartphones have apps to decode QR codes (here’s one for Android phones.) To decode a QR code, open the app (ask it to scan from camera) and it’ll open your camera. Aim the camera at the code and take a picture. The app will decode the QR code for you and turn it into whatever it was before it was decoded.
Most phones’ QR Code reader apps also let you create QR Codes. There are some web services that do this too.
And that’s really all there is to QR Codes. If you’re a techie you can read the nitty gritty details.
HCCBs
High Capacity Color Barcodes, or HCCBs, do the same thing as QR codes except they’re more colorful.
Microsoft has an implementation of HCCBs called (rather creatively) Microsoft Tag (I think USA Today has some Microsoft Tags on its front page.)
Like with QR Codes, you need a smartphone app to encode and decode these.
In my mind the Microsoft Tag is a non starter. QR Codes have gained tremendous uptake over the last few months but there are many examples of bad usage. To be of any value in a marketing campaign the QR Code when scanned MUST deliver value to the scanner. What is the use of taking someone to a badly mobile optimised webpage? The idea behind QR Code is to connect and engage the consumer
Agreed. Many times QR codes are just used as gimmicks to get people’s attention. The Microsoft Tag has seen some usage (mostly because it’s a Microsoft product) but I can imagine many people don’t want to bother downloading yet another app just to scan one code.
