This document provides an overview of a group project on QR codes. It introduces the group members and outlines their roles and responsibilities. It then provides a flow or outline of the presentation, including an introduction to QR codes, how they work, examples of their daily usage, a mind map, survey results, and possible future developments. It discusses how the group will create a mind map, conduct a survey, search for information, make a PowerPoint, write a script, and analyze survey results. The document assigns specific tasks to each group member.

4. Introduction to QR code
Invented by a
company called
• two-dimensional code
Denso Wave in
1994
• Having camera
Smartphone
•  QR code become more popular
Can be printed • Convenient
everywhere • load the message everywhere

5. How the QR code works
• Download a QR code (e.g. barocde scanner)
scanner from
• -appstore (for Apple )
camera • -playstore (for Android)
• Run the scanner programme and place the
camera in front of the QR code
• recognize the information
Position • a reference pattern , preventing error when it
pattern is being scanned from different angles.
• message is interpreted automatically
Data • strong error checking and correction ability.
Pattern

6. How the QR code can perform
error checking
 In this QR code, you can actually see
a colorful icon inside it. This QR
code still works as it’s 2D coding
pattern actually contains several
copies of the original data. Some
can be sacrificed to give space to
some colorful icons. You can do
advertising while spreading
information.
 It also means that the QR code can
work even if some of the patterns
are destroyed. The redundancy of
the code makes it durable and
became a reliable way the contain
information.

7. Examples of daily usage of QR code
product label and e-buying

8. Some other examples for the usage
of the QR code
Many many
website,
website text, video,
image,
animation…
characters
 These types of QR code are commonly generated by
companies for commercial usage
 Often exposed to their clients, including passer-bys.

9. Some other examples for the usage
of the QR code
2.Information packaging
Images
In some hospital, words symbols
where hundreds of
1 single
illness report card of patients QR
passing over and over, the information code!
of patients are stored in the format of a printed
QR code.

14. The importance of the QR code
Easy to be generated with the use of
Bar code QR code easy-found appropriate programme.
Connecting virtual world and
reality
Contains infinite and unique
pattern for storing messages in
different kinds of formats
Easy to be detected and preceived
