Hey!
Readers
Now
days a craze for QR Code has begun. Every advertisement has a QR Code embedded
in it which usually takes you to the link of the product’s demonstration movie
on YouTube®. During this thinking and research I got a program ( A
basic HTML one) which could generate the QR Code for your Website , Facebook Fan
page , Google+ Profile or any link you want. You can even make it for
a text, address or number.
If
you want one contact me on details at the end of post.
Beginning with a Bar Code Reader I’ll be telling
the basic funda how it works then we’ll move on to QR Code Reader.
A barcode scanner is composed of three parts: the
illuminator, the decoder, and the sensor/convertor. The barcode scanner
illuminates the barcode with red light using the illuminator system. The
sensor/convertor part of the scanner then detects the reflected light. Once the
light is detected, an analog signal is generated. This signal contains varying
voltage based on the intensities of the light reflection. The analog signal is
converted by the sensor into a digital signal. The digital signal is then
interpreted by the decoder. The decoder then sends the information to the
computer attached to the scanner.
In the case of QR code scanner, the decoder sends
the information to your mobile phone instead of a computer. The app you
download for your phone that is a QR code scanner contains the illuminator,
which is the red light that runs across the screen when you open the app. The
sensor and decoder then work to decode the QR code. Then the decoder sends the
information to your phone, and you will be able to see where the QR code was
supposed to take you.
The way the scanner reads the reflected light it
actually a lot more complicated than the way that I simply described it, but I
think it's fascinating that all you have to do is download a free app and all
of a sudden your phone is a barcode scanner. The barcode was first patented in
1952, and now almost every person with a smart phone carries around their own
barcode scanner with them every day. Since this scanning technology is so
easily accessible with most phones, QR codes as a marketing tool seem like they
will be around for a while.
Thank You!
