Development of Applications for Generating and Reading QR Codes for the Micro1 Model

The paper provides an overview of barcode technology, describing the milestones of the technology evolution, with brief history outlines, depicting main points of barcode systems and highlighting emerging technologies having affected the way towards development of modern access codes. The underlined principles of QR are presented via code operations performed by example of a relatively simple code model widely known as Micro QR Model 1. The practical result obtained in the research was a simple application developed, which encodes a short piece of information into images according to the principle of Micro 1 model QR coding. Python-based encoder and decoder securely generating and processing Micro-1 codes was created. An essential part of the application code, application interface and a security block request are presented in the paper.
