2. WHAT ARE QR CODES? HOW IS IT MADE?
QR code (from Quick
Response Code) Is a way of
storing data that has 4 encoding
systems instead of one like in
the bar codes. It became
popular because it was easy to
read and it had lots of more
capacity than a bar code, also it
was great for all kinds of
marketing.
example
It is made with square dots in a blank
that can be scanned by lots of the new
devices and lots of applications.
3. THE HISTORY OF THE QR CODE
The QR code system was invented in 1994 by Denso Wave. Its purpose was
to track vehicles during manufacture, it was designed to allow high-speed
component scanning. Although initially used for tracking parts in vehicle
manufacturing, QR codes now are used in a much broader context, including
both commercial tracking applications and convenience-oriented applications
aimed at mobile-phone users.

4. CARD READER
A card reader is a data input device that reads data from a card-
shaped storage medium. The first were punched card readers, which read the
paper or cardboard punched cards that were used during the first several
decades of the computer industry to store information and programs for
computer systems. Modern card readers are electronic devices that can read
plastic cards embedded with either a barcode, magnetic strip, computer
chip or another storage medium.
A memory card reader is a device used for communication with a smart
card or a memory card. A magnetic card reader is a device used to
read magnetic stripe cards, such as credit cards. A business card reader is
a device used to scan and electronically save printed business cards.
5. BANK CARD READERS
Some banks have issued hand-held smartcard readers to their customers to
support different electronic payment applications:Chip Authentication
Program (CAP) uses EMV banking cards to authenticate online transactions
as a phishing countermeasure. Geldkarte is a German electronic
purse scheme where card readers are used to allow the card holder to verify
the amount of money stored on the card and the details of the last few
transactions.
6. WHAT I THINK THE FUTURE WILL BE
I think the qr code has a lot of
future and a lot to come but the
readers are going to desapear.
