Description

technical field [0001] The invention relates to an electronic data processing technology, in particular to a hand-held data collection terminal. Background technique [0002] Automatic identification technology is a method or means to automatically read and input data into a computer. It is a comprehensive science and technology based on the development of computer technology and communication technology. The rapid rise of barcode technology, as a revolutionary high-tech, is generally accepted by people, precisely because it provides an effective means of fast and accurate data collection and input through the "sharp tool" of data collection terminals, and solves the problem of The "bottleneck" problem caused by the slow speed of manual input of computer data and high error rate. [0003] Through hardware technology, software technology and the organic combination of the two, the data acquisition terminal realizes barcode scanning, decoding, and data communication with the...
