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 Japanese Corporation Denso Wave.*QR codes were released in 1994 to Toyota for tracking vehicle parts during manufacturing.*2D codes were accepted internationally between 1997 and 2004.
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 *
**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.*The method prevents enlargement of code symbol area, negating the increased production cost this entails.
*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, websites, contests to enhance programs and exhibits* Link library audio tours* Link to library’s reference services and other contact information* Link to specific collections (teen, career, etc.) for more information about the collection (Cordova).* Link to author interviews or book reviews on audiobooks* Used on handouts that link to mobile sites* Used with permanent art or art shows within the library to link the artist web site* Provide catalog records to obtain the location and the call number of the item* Provide link to video trailers on DVD cases* Provide video tutorials for library services.* Placed in the stacks to direct the user to related online sources* Placed on or near study rooms to connect to the reservation form* Used on bookmarks and placards around campus or the community to market library services* Used on Twitter and Facebook for an online presence (Cordova).* Offer information about the library, such as hours, checkout procedures, and overdue/fine information. (Cordova).
Academic Libraries *Link to mobile versions of websites *Access to an item’s record to provide the title of the record, location of the item, and its availability. *Renew resources *
Public Libraries * Codes link to audiobooks that can be wirelessly downloaded onto smartphones * Codes used to find mobile apps * Codes located on bookshelves to link subject guides *
School Libraries *Can be placed throughout the school *Promote events by linking websites *Link to book reviews for students to read *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 that users might need information about.*QR codes can store quite complex information in a small matrix. *
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. *
**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 (teens to late twenties), in part because the codes can only be scanned using smartphones, and young people are more likely to own and be a smartphone.
