A QR code, or quick response code, is a 2D barcode developed in 1994 that allows users to access information using a smartphone or scanner. It can store various data types including text, URLs, and payment information, gaining further popularity during the COVID-19 pandemic for facilitating contactless transactions. The integration of QR codes in libraries has enhanced resource access and management, although challenges in user knowledge persist in some areas.

2. QR code definition
 A QR code is an abbreviation for quick response code which is a
readable code that allows the person to view information about
a particular item using a scanning machine or phone camera
 It is a method of encoding and classifying items, making
information storage and access easier and more organized

3. QR code History
 The QR codes is 2D symbols developed by Toyota Denso wave
1994 with first aim that symbol is easily decoded by scanner
instrumentation at huge speed with vertical and horizontal
directions.
 There are mainly four kinds of data such as numeric,
alphanumeric, byte or binary and Kanji which are encoded into
information or through supported extensions.

4. QR Mode
1. Numeric mode - This is for decimal digits 0 through 9. Numeric mode is the
most effective storage mode, with up to 7,089 characters available.
2. Alphanumeric mode - This is for decimal digitals 0 through 9, plus uppercase
letters A through Z, and symbols $, %, *, +, –, ., /, and : as well as a space. It
allows up to 4,296 characters to be stored.
3. Byte mode- This is for characters from the ISO–8859–1 character set. It allows
2,953 characters to be stored.
4. Kanji mode - This is used to encode characters in Japanese. This is the original
mode, first developed by Denso Wave. However, it has since become the least
effective, with only 1,817 characters available for storage.

5. QR code can store different types of
information
 Simple text - welcome messages at conferences
 Addresses - personal home address, business address
 Phone numbers - personal telephone number, your college phone number
 E-mail addresses - personal or academic accounts
 URLs - addresses of websites or specific web pages
 Links to apps - found in app stores such as Google Play or Apple's App Store
 Payments - QR codes can store information about your bank account or credit card
 WiFi authentification - QR codes can be used to store WiFi networks
authentification details such as password and encryption type: when you scan such
a QR code using your smart-phone, it can automatically join that network
• Or any another type of text

7. QR code popularity
 QR codes become even more popular during the COVID-19 pandemic because it
facilitated contactless dining, shopping, and other activities.
 Due to its success because it is easy to use, doesn’t require more than a
smartphone, and allows quick access to information, most shops have continued
to use QR codes post COVID-19 pandemic.

10. Common uses of QR Codes
 Amplify your events

11. Examples of QR code application
Application scenes in the traffic
field Application scenes in the medical
field

13. QR code in Library

14. Scanning QR code
 QR code makes it capable of presenting all book-related
information within seconds of scanning the code.
 Integrating the quick response code will allow easier
access to online content, library stacks, memberships,
electronic libraries, and journal articles

15. Some examples of QR code in
Library practice

16. WORLDWIDE SCENARIO OF QR CODE IN LIBRARY
Name of the Library QR Code in library practices
Lafayette College Library
Used QR codes for their 2010 Open
House event geared to first year
students, "Where in the Library is
Carmen San Diego: An Interactive
Mystery Game". Students had to collect
QR coded-clues from librarians stationed
throughout the library.
Syracuse University Library Learning
Commons
is using QR Codes on their bookmarks,
tabletop signs, and on the flyer
advertising their virtual tour - see our
set on Flickr
Half Hollow Hills Community Library
Uses data matrix codes on end stacks to
lead patrons to subject guides on the
web.

17. QR code made librarian’s job easier
 the implementation of the QR code method in libraries was
successful and has made librarian’s jobs easier where they were
able to enter books into the system using the code and manage
the issuing and returning of books through the QR code instead
of the traditional library numerical system.
 However, we need to keep in mind that not all experiences are
similar. For instance, in an experiment in Nigeria, many
librarians (around 50%) were unable to use the QR code because
they did not have the knowledge required for it which made the
experience difficult and unsuccessful.

19. Conclusion
 To facilitate the processes of storing and finding information
concerning library resources, we can adopt the use of QR codes in
libraries which will assist both librarians and users. It will allow users to
have a more user-friendly experience in libraries due to the ease of
using a QR code since it only requires a phone, a software for reading
the code, and an internet connection.
 Furthermore, this will assist libraries to store data online regarding
library resources and will allow them more time for other tasks. Today,
almost all stores have adopted quick response codes and I believe it is
time for libraries to do the same.
