There are a number of ways to scan a QR Code. The usual way is to use an imaging scanner to scan the code. Another wide-spread way is to use a smartphone. With the boom of smart phones in recent years, QR Code becomes a media hype for some time. People would use QR Code to access a website, read information about a particular product, and to register for an event on the spot.

This app is very capable of reading QR Code from a magazine, a poster, a business card, or even a wall.

This makes QR Code becomes tremendously helpful for any companies providing streaming contents to the users.

Phuc, is the picture a mock-up your plans for an actual business card? Neat picture, though it would be easier to read if the font was increased. Could you provide links to the Layar app and Denso Wave's claim to inventing QR codes?
ReplyDeleteYou state that QR codes are a current hot trend, but how do you see this technology remaining relevant in the future? Is there any competing 2D bar-codes or other technology that might replace it? Or do you think that it will become irrelevant with machine vision recognizing objects without the need of a code?
