QR碼: 像條形碼, 只有更好

Quick Response Code
快速響應碼

QR碼, 或 快速響應代碼, 都是時下風靡一時. 你知道嗎, 那些黑色和白色條碼尋找那一樣的東西出現在雜誌, 海報, 甚至一些T卹.

QR碼其實是相當類似條形碼: 這是一個形象, 數據編碼 喜歡 網址, 電話號碼, 話, 和更多. 你甚至可以拍照和排序的把它變成一個QR碼 (畫面被上傳到互聯網和QR碼的編碼圖片的URL。) 當然,你失去了一些審美價值, 但嘿.

但, 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.

Using a QR Code is like putting something in a box and then taking it out.

Most phonesQR 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.

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.

  1. 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

    1. 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.
