*QR code stands for Quick Response.
*QR codes are two-dimensional (2D)
bar codes developed by the Japanese
Corporation Denso Wave.
*QR codes were released in 1994 to
Toyota for tracking vehicle parts during
manufacturing.
*2D codes were accepted internationally

3. A QR code is a 2D barcode
that...
*has a large information capacity
*holds up to 7,089 characters
*stores data in both vertical and
horizontal directions.
*popularly used for storing URLs
*

4. *
*The intention was to develop a symbol code
more easily read by scanners than
traditional codes.
*The codes were developed in response to
the need for more data storage capability
within a smaller space. Bar Code Stacking
*Technology emerged through progression
from the stacked bar method (stacking
multiple bar codes).
*2D codes are the result of utilizing the
increased information density matrix
method.

6. *A QR code is generated with QR code
creation software and a specialized QR
code printer used in conjunction with QR
code scanner.
*A person takes a picture of the QR code
using a camera, usually on a
smartphone, to access the data stored in
the code. Then, the image is processed
using a QR code reader (smartphone
application).
*
*Most QR code applications are compatible
with major cell phone providers and
FREE!

8. Symbol Version
*Versions range from Version 1 to
Version 40
*Each range has its own
maximum data capacity
*The more information that is
stored in the symbol necessitates
*
more modules and a larger range

9. Error-Correction Level
*There are four potential levels
(L, M, Q, H).
*The greater the correction
capability, the more data created
to be stored in the code
*Level M (15% recovery) is the
most frequently used
*

10. Margin (“quiet zone”)
*Margin refers to blank
space around symbol
*QR code specifications
require a minimum four-
module wide margin on all
sides for accurate reading
*

11. * Example: Creating QR Code to encode 50 alphanumeric characters
* Specify the error correction level as the standard "M".
* Obtain a version from the Version and maximum data capacity
table (find the intersection of alphanumeric characters and Level
M). → Version 3 capable of storing 50 or more characters. (Version
2 with Level M holds only 38 characters.)
* Use a printer with 400 dpi resolution. → 0.254 mm when printed
with 4-dot configuration.(Equation: 25.4 mm/inch ÷ 400 dpi × 4
dots/module = 0.254 mm/module)
* 4. Version 3 = 29 modules, therefore, the size of QR Code is 29
*
modules × 0.254 mm/module = 7.366 mm.
* Secure a four-module wide margin. 7.366mm + 0.254mm/module ×
8 modules =9.398mm
* In other words, the required QR Code area is 9.398mm2.

* Link to songs, web sites, contests, etc. that can enhance exhibits.
* Codes in the stacks that direct the user to related online sources.
* Link library audio tours.
* Handouts that link to mobile sites.
* Links library’s reference services and other contact information.
* Permanent art or art shows within the library can link to the artist web site.
* Catalog records that can provide the location and the call number of the item
* Video trailers provided on DVD cases.
* Audio book cases can link to author interviews or book reviews.
* Codes can be placed on or near study rooms to connect to the reservation form.
* Video tutorials for library services.
* Bookmarks, placards around campus or the community to market library services.
* Codes can link specific collections (children’s, career, etc.) to more information
about the collection (Cordova).
* Offer information on the library such as hours, check out procedures, and fine
information. (Cordova).
* Can be used on Twitter and Facebook for an online presence (Cordova).

13. *
* Academic Libraries
* Link to mobile versions of websites
* Found in item record that provide the title of the
record, location of the item, and it’s availability.

14. * Public Libraries
* Links located on public transportation to
audiobooks that can be wirelessly downloaded
onto cellphones
* Codes used for find mobile apps
* Codes located on bookshelves to link subject
guides
*

15. * School Libraries
* Promote events by linking websites
* Can be placed through-out the school
* Promote potentially embarrassing information in
a non-threatening way

17. *QR Code is an open format.
*There is no need to write down vital details.
A simple scan captures the desired
information.
*QR Codes can be used to store website
addresses and URLs that can appear in
magazines, on signs, on buses, on
business cards or just about any product
* *QR codes can store quite complex
that users might need information about.

18. Weaknesses
* No universal standard.
* Not everyone is aware of QR Codes or how they
work.
* Not everyone owns a camera phone.
* It is impractical to expect students to be able to
capture coursework information from QR codes
without some support.
*

19. Will these codes continue to be used or will they
be replaced with the next best thing?

20. *
*Awareness for QR Codes is relatively strong.
*65% of smartphone users say they have
seen a QR code.
*Out of smartphone users who have seen a
QR code, 56% have seen them most often on
product packaging, 45% have seen them in
magazines, 45% have seen them on
coupons, and 27% have seen them in
newspaper ads (27%).
*QR codes are popular with young people
