Hard to read on the slide but should work find like this in another format, with the ability to zoom into each aspect.

Using qr codes in libraries
* Rita Boh Jennifer Charbonnet Melissa Minchey Emily Rush Julie Weber
**QR code stands for Quick Response.*QR codes are two-dimensional (2D)bar codes developed by the JapaneseCorporation Denso Wave.*QR codes were released in 1994 toToyota for tracking vehicle parts duringmanufacturing.*2D codes were accepted internationally
A QR code is a 2D barcodethat...*has a large information capacity*holds up to 7,089 characters*stores data in both vertical andhorizontal directions.*popularly used for storing URLs *
**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.
*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!
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
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 *
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 *
* 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).
** 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.
* 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 *
* School Libraries * Promote events by linking websites * Can be placed through-out the school * Promote potentially embarrassing information in a non-threatening way *

*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.
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. *
Will these codes continue to be used or will they be replaced with the next best thing? * http://news.yahoo.com/blogs/this-could-be- big-abc-news/qr-codes-things-185409346.html*
**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
