Currently the market still using barcode. One of the advantage of using barcode is it is easy to maintain and count, computerise made easy that hour of time. Even today, a lot of package comes with a barcode and calculating made easy too with barcode scanners.
However, in 1994 Japan created another code that is even better, contain a lot more information than a barcode can do – QR Code. I personally has been looking out for the QR code development, and hoping that one day, it will arrive in my country, which of course I would have reason to cut down lots of paper in just one small card. Believe it, in Japan, QR code is so common that even a mobile phone can scan the code and read the content.
Recently while my wife and I working on our legal document, her country started to use QR code too on the letter they (government) issued us. I mean, come on, it’s Indonesia, some say it is third World country?… Maybe no eh?
