Data Matrix is a matrix (2D or two-dimensional) bar code which may be printed as a square or rectangular symbol made up of individual dots or squares. This representation is an ordered grid of dark and light dots bordered by a finder pattern. The finder pattern is partly used to specify the orientation and structure of the symbol. The data is encoded using a series of dark or light dots based upon a pre-determined size. The minimum size of these dots is known as the X-dimension
Who can use Data Matrix codes?
Three things are required in order to successfully decode a QR code: a Smartphone, a Data Matrix code scanning application, and a connection to the Internet (either through the phone’s data plan or over a site-generated wireless network)
In order to use Data Matrix codes, you need to have a cell phone capable of running decoding software. These phones can download and install applications, can access the Internet, and have cameras. These types of phones are loosely referred to as “Smartphones”; the most common examples are iPhones, BlackBerries and Android phones.
There are a number of applications which can be used to decode a Data Matrix code, all of which work in similar ways. We have chosen to use ScanLife, a free app which has versions for a wide range of phones. Going to the website – http://getscanlife.com- on a phone’s Internet browser will automatically detect the type of phone and guide you to the appropriate version of the application.
Because the Data Matrix code is a link to online content, you need to be able to connect to the Internet in the location where the codes are placed. Smartphones can connect to the Internet in two ways: through a 3G data connection, or through WiFi
