The recent popularity of camera phones has opened up a new field of use for machine-readable 2D barcodes. You can print a code on an everyday object and interact with it using a camera phone. Interactions initiated by scanning the 2D barcode with your phone's camera. And the reaction can be anything from simply retrieving information to triggering an action. Given the low cost of 2D barcode printing, there are many possible applications that could build on this. One such application is examined in this thesis and aims to improve the usefulness of regular cash register receipts. The idea is to print a 2D barcode on receipts that contains the purchase information in digital format. This is supposed to help customers with receipt management or with more detailed accounting. This hypothesis is evaluated by developing a prototype implementation of a receipt reader. This prototype is based on two Java libraries for decoding Data Matrix and Quick Response codes. The main conclusion of this evaluation is that the libraries used were able to store approximately 42 shopping items in a 2D barcode. There are tradeoffs that can be implemented to increase capacity when needed, which helps make the assumption valid. In the era of technological progress and the speed of communications, the words "power" and "information" walk side by side. Organizations from various sectors such as manufacturing, trade or services and their affiliated institutions have already understood that focusing only on their own interests is not very intelligent. That's not good enough in this internationalized competitive society. A company's effort will be of no use if there is no powerful nation with purchasing power to purchase its products and services efficiently. Likewise, if the company is unable to meet all requirements or is unable to implement new technology, its future may be in jeopardy. GS1 (formerly EAN.UCC) organizations with the global EPC network aim to improve quality, supply chain efficiency and train professionals, such as healthcare centers and automotive industry with this new technology called EPC/RFID ( Product Code electronic/radio frequency identification). EPC/RFID professional and related business training is currently taking place with an emphasis on developing the education and training of this new automatic identification system. From
