  • Data Matrix and Aztec Code have significantly lower capacity (4096 alphanumeric characters for QR Code, 3067 for Aztec Code and 2335 for Data Matrix), so if you would like to encode a lot of text, select QR Code.
  • Aztec Code may not support UTF-8 characters for the time being, so if you encounter such a problem try QR Code or Data Matrix. Another caveat of Aztec Code is that, it is not supported by most of the scanner programs out there. As for Kanji and Cyrillic characters, only QR Code should support them.
  • Micro QR Code cannot hold more than 35 numeric and 21 uppercase alphanumeric characters, and it can hold even less characters when you use lowercase characters.
  • High Capacity Colour Barcode (HCCB) is the name coined by Microsoft for its technology of encoding data in a 2D "barcode" using clusters of colored triangles instead of the square pixels traditionally associated with 2D barcodes.[1] Data density is increased by using a palette of 4 or 8 colors for the triangles, although HCCB also permits the use of black and white when necessary. It has been licensed by the ISAN International Agency for use in its International Standard Audiovisual Number standard,[2] and serves as the basis for the Microsoft Tag mobile tagging application.
  • Created by Toyota subsidiary Denso Wave in 1994 to track vehicles during the manufacturing process,[2] the QR code is one of the most popular types of two-dimensional barcodes. It was designed to allow its contents to be decoded at high speed.[3]

  • Since QR Code carries information both horizontally and vertically, QR Code is capable of encoding the same amount of data in approximately one-tenth the space of a traditional bar code.
  • QR Code is capable of 360 degree (omni-directional), high speed reading. QR Code accomplishes this task through position detection patterns located at the three corners of the symbol. These position detection patterns guarantee stable high-speed reading, circumventing the negative effects of background interference.
  • QR Code can be divided into multiple data areas. Conversely, information stored in multiple QR Code symbols can be reconstructed as single data symbols.One data symbol can be divided into up to 16 symbols, allowing printing in a narrow area.
  • EncodingThe diagram below illustrates the placement of the message characters within a QR code. Starting from the lower-right corner, the first four bits define the encoding used (in this case, 8 bits per character). Next is the length of the message (17; dark stands for 1, but the masking process used in this symbol inverts alternate rows). Following that is the message itself, then the end-of-message marker, and finally the error-correcting codes.

  • QR CODESDavid Harvie and Krista RobinsonStratford Public Library
  • Overview Matrix Codes Types of Matrix Codes Why QR Codes QR Codes - Characteristics and Structure Examples of Use in Libraries Various QR Code Readers Where to make your own Concerns/Issues
  • Matrix Codes A matrix code, also termed a 2D barcode or simply a 2D code, is a two- dimensional way to represent information. It is similar to a linear (1-dimensional) barcode, but can represent more data per unit area. (Source: Wikipedia)
  • Data Matrix Codes
  • Aztec Code
  • Micro QR Code
  • High Capacity ColourBarcode (HCCB)
  • Quick Response (QR) Codes
  • Why QR Codes?
  • QR Codes – Data SetsQR Codes are capable of handling numerous types of data:  numeric and alphabetic characters  other character sets - Cyrillic , Kanji, etc.  symbols  Binary  control codes
  • QR Codes - Storage Efficient – one tenth the size required for traditional bar code. QR Code Data Capacity Numeric only Max. 7,089 characters Alphanumeric Max. 4,296 characters Binary (8 bits) Max. 2,953 bytes Kanji, full-width Kana Max. 1,817 characters
  • QR Codes - 360º Readable from any direction.
  • QR Codes – Error Correction Data can be restored even if the symbol is partially dirty or damaged. Different levels of error correction are available:  Level L - 7%  Level M - 15%  Level Q - 25%  Level H - 30%
  • QR Codes - Linkable Structured Append Feature
  • QR Codes - License The use of QR codes is free of any license. The QR code is clearly defined and published as an ISO standard. Denso Wave owns the patent rights on QR codes, but has chosen not to exercise them.
  • QR Code - Structure
  • QR Codes - Encoding
  • Where Will You See a QR Code Everywhere!  Subways & Shopping –  Billboards see Tesco QR Code video  Business cards  Airline boarding passes  Print ads  Contests  Packaging and labeling  Self guided tours  Restaurants / museums / tourist  … and in Libraries! attractions http://2d-code.co.uk
  • Uses & Examples Advertise Databases  Preferably with mobile versions
  • Uses & Examples Advertise Apps  Take the user directly to the iTunes store for BookMyne or Overdrive Media Console Mobile
  • Uses & Examples Advertise Events  Map to event  Facebook Event or website details  Add event to a scanner’s calendar
  • Uses & Examples On Business Cards  Links to our mobile website  Create a vCard or meCard to add contact info directly to a mobile device
  • Uses & Examples Hide Graffiti
  • Uses & Examples In Buses  In Contra Costa Library System, billboards with QR Code that links to a mobile site for their Overdrive site http://goo.gl/W98RV
  • Uses & Examples Library Tours  Each scan reveals information about that area of the library  Design to work on a mobile site or in a youtube video Syracuse University
  • Uses & Examples In Library Catalogues  Scan & bring up an item’s location = no scrap paper! – Ryerson University Library & Archives
  • Uses & Examples On bookmarks linking to staff book reviews On book covers to “read alike” lists In Books with the Phone Number / website embedded for renewals Link to your RSS feed for easy subscription SMS/Email for text-a-librarian or email a librarian services Check availability of study rooms Wifi login link or instructions Create predefined searches at a book display Within a press release to take readers to a specific page or download on your website
