In the article "Matrix Codes" by David Warlick, a new technology is presented to the public through a smart phone application. This app allows for a person to scan a two-dimensional code and bring up all related information like a web site for that store or in David's use bring up a brochure. Devices like this can easily increase efficiency of working because instead of having to look something up they just have to scan the code and the information comes up automaticlly. Clearly, devices like the two dimensional code scanners can help decrease the time that people have to spend on working through the Internet to find what they need.
