Barcode scanner, also known as barcode reader, barcode scanner, barcode scanner, barcode scanner and barcode reader. It is a reading device used to read the information contained in the bar code. It uses optical principles to decode the content of the bar code and transmit it to a computer or other device through a data line or wirelessly. It is widely used in supermarkets, logistics express, libraries, etc. to scan barcodes of commodities and documents.
The laser scanner can be used for non-contact scanning very well. Usually, the laser reader is the only choice when the reading distance exceeds 30cm; the laser has a wide range of bar code density, and can read irregular bar code surfaces or through glass Or transparent adhesive paper reading, because it is non-contact reading, so it will not damage the bar code label; because of the more advanced reading and decoding system, the first reading recognition success rate is high, the recognition speed is faster than the light pen and CCD, and the printing quality is not good Or fuzzy bar code recognition effect is good; the bit error rate is very low (only about one in three million); the laser reader has good shock and drop resistance, such as: SymbolLS4000 series scanner, which can be 1.5 meters away from concrete .
