![STRUCTURE OF QR CODE
QR Codes are actually black modules in square patterns on white background. QR Codes
consists of many areas that have specific importance.
[1] Finder Pattern
[2] Alignment Pattern
[3] Timing Pattern
[4] Quiet Zone
[5] Data Area

QR codes in libraries (By Gaurav Boudh)
- 1. QR CODES IN ACADEMIC LIBRARIES Gaurav Boudh
- 2. QR stands for Quick Response code Invented in 1994 by the Toyota Motors subsidiary Denso Wave to track vehicles and parts during the manufacturing process It is a two dimensional barcode, typically seen as a white square with black geometric shapes It is basically a type of barcode which is readable by any camera-enabled smart phone
- 3. QR Code. Scan or input the URL (http://www.du.ac.in/d u/index.php?page=centr al-library) to view Delhi University Library System Source:https://www.qr-code-generator.com/

- 5. Pattern: The Three big squares which are found in the corners of a QR Code are used for identifying size, position and angle. Alignment Pattern: It is used for modifying the distortion of QR code. Timing Pattern :The pattern made up with black and white modules. This pattern is used for determining the central coordinate of each cell in the QR code. Quiet Zone: It is part of a QR Code. It is a margin space which is used to detect the QR code. It consists of four cells and is used for quiet zone. Data Area :This element has error correction functionality. It stores data converting into binary digits 0-1. It consists of array of rows and columns.
- 6. Maximum character storage capacity (40-L) Character refers to individual values of the input mode/datatype Input mode Max. characters Bits/char. Possible characters, default encoding Numeric only 7,089 3⅓ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 Alphanumeric 4,296 5½ 0–9, A–Z (upper-case only), space, $, %, *, +, -, ., /, : Binary/byte 2,953 8 ISO 8859-1 Kanji/Kana 1,817 13 Shift JIS X 0208
- 7. The main advantage of a QR code is its versatility. They can be used for anything and everything. Free, can embed many types of media, easy to use. Does not require understanding of writing code. A fun and effective way of delivering enhanced information directly and conveniently to users. Can trackhow manytimesthe QR code is scanned for statistical purposes.
- 9. Data Restoration-Occasionally QR codes and bar codes become damaged or they may get dirty. Barcode reader will not be able to scan a damaged or dirty code whereas up to 30% of code words in a QR code can be restored depending upon amount of damage.

- 10. Expert in Scan Position and Speed:-Barcode must be scanned in the correct position. But QR code can be scanned from any position. This is due to the three position detection patterns located in three corner of the code. The reader will locate these three detection patterns and know how to correctly read the code. This feature speeds up the time needed to scan objects.
- 11. Four things are required in order to successfully decode a QR code: QR code Generator Smartphone, Desktop (with a camera), QR code Scanning Software application, and Internet Connection (either through the phone’s data plan or over a site-generated wireless network).
- 12. Generator (Desktop) Reader (Desktop) • Quick Mark • Zxing Decoder • Quick Mark • Zxing Decoder
- 13. How it works ? • Phone with camera & Internet access • Download & install a QR Code reader on your phone • Phone’s camera acts like a scanner, allowing it to “read” the code • Once scanned by your phone, the codes can provide you with contact information, text messages, contents of an ebook, mobile website etc
- 14. • Pinpoint the information that you wish to share • Locate a user friendly QR Code generator website • Fill in appropriate content and information • Test the QR Code • Save the QR Code image on your computer • Share your QR Code with the world
- 15. There are plenty of free QR code generators websites. Some websites are: •KAYWA Generator - http://qrcode.kaywa.com/ •QR Generator - https://www.the-qrcode-generator.com/ •Go QR Generator - http://goqr.me/ •QR Stuff Generator - http://www.qrstuff.com/ •Bee Tag QR Generator - http://www.beetagg.com/
- 16. QR codes can be used in library books, journals, CD-ROMs, ticketing, entertainment and transport ticketing, VCard information, commercial tracking, product/loyalty marketing and in-store product labelling. So we can say that QR code can be used in a variety of ways as per need. The main aim of using QR code is to give brief message to the users.
- 17. • QR Code Link to e-Contents • Linking to the online surveys • Linking to Library Contests • On Library Stacks, Journal Areas that point to online electronic holdings • Linking to Library Audio tour for Orientations • Linking to Library Blog, Websites • Linking to Digital Library • Linking to Library Maps • Linking to Library Wi-Fi Network etc.

- 20. Wi-Fi Network Libraries creates QR codes that contain Wi-Fi network credential and paste it within the library. After scanning user will connect to internet connection. Source:www.aiktcdspace.org:8080/jspui/bi tstream/.../1505/3/QR%20SEM%20- %20PPT.pdf m
- 22. By scanning QR code user can easily access libraries Article Abstract Database. Source:www.aiktcdspace.org:8080/jspui/bi tstream/.../1505/3/QR%20SEM%20- %20PPT.pdf
- 23. Web Supplements Most of the publishers provides the web suppliments for instructors and students.Library finds out those books and generates QR codes for them and paste on the books. Example:McGraw Hill Source:www.aiktcdspace.org:8080/jspui/bi tstream/.../1505/3/QR%20SEM%20- %20PPT.pdf
- 24. CD Library By scanning QR code we can access the CD/DVD’s content of the book. Source:www.aiktcdspace.org:8080/jspui/bi tstream/.../1505/3/QR%20SEM%20- %20PPT.pdf
- 25. Benefits of QR Code • It is available for free. • one can create the QR code using free software. • It is very fast to access the information embedded with the code. • Easy to read the QR code. • The nature of QR code is versatility.
- 26. Limitations of QR Code Lack of familiarity among people and users. Need of scanning device. If you want to access the information in the QR code, you should have a device that supports the QR code scanning facility. It takes time to scan the code embedded in the QR code. You need a QR code reader software. It needs an internet connection.
- 27. Conclusion Libraries are now being very challenged by the development of various technologies. In this present era, the new technology like QR code demands the changes of information handling in the library. The user would have easy access to most current and necessary information related to the library by using QR code. So to make the effective use of QR code among the user community, library professionals must organise user awareness program, orientation programme, etc.
