In our daily life, more and more goods are circulating in the market, and the black and white barcode on the goods is like the ID number of the goods, so that we can know its information and ensure the safety of the goods. Quality can trace the source of goods and bring great convenience to our lives. And the bar code reading device - the scanner is playing a very important reading role, used to connect us with the goods, to achieve information interaction. The increasing variety and variety of bar code scanners have made it difficult for many users to purchase a scanner. Here, in order to facilitate the selection of the scanner, I will explain to you the classification, function and simple use of the scanner.
1. Laser scanner. There will be wired scanners and wireless scanners in the middle, which are free to choose according to your own environment and practical application. The main advantages of the laser scanner are the fast scanning speed, long scanning distance, fast decoding, and low bit error rate. It is the most widely sold type of scanner on the market. In the process of using, the red laser line emitted by the scanner can scan the barcode on the commodity to read the commodity information. Its adaptive bar code is more of the actual bar code in our usual application, such as the bar code of the goods in the supermarket, the bar code on the courier, and the bar code on the ticket, including the bar code on various cards.
2, red light scanner, also called CCD scanner. It will also be divided into wired and wireless scanners. The main advantage of red light is that it scans barcodes that are not easily read by various laser scanners, such as damaged or defective barcodes, coating or plastic sealing on barcodes, and there are also barcodes printed on some metal objects. Strong, the barcode inside the screen, including the bar code on the mobile phone screen, computer screen, tablet (Pad), because of the particularity of the screen, so the laser scanner can not recognize these barcodes, read in the red light scanner It has also become easy to read. Currently, it is more common in special industries such as tobacco and medicine, as well as in the application of Alipay and WeChat payment barcodes.
3, two-dimensional scanning gun. Also divided into wired two-dimensional scanning guns, wireless two-dimensional scanning guns. I have seen the above-mentioned scanner introduction. This scanner is relatively easy to understand. It refers to a scanner that can scan two-dimensional codes. However, the QR code scanner is fully compatible with all one-dimensional codes.
Simple operation:
1. Wired scanner. Before using the scanner, connect the scanner to the computer with the data cable, open the text document or other input documents, start the scanner, scan the barcode, and upload the barcode information to the computer. The connection is successful and works fine.
2, wireless scanner, first insert the wireless receiver of the scanner into the computer, and then the wireless receiver driver is automatically installed on the computer, start the wireless scanner, the scanning process is the same as the wired scanner.
3, Bluetooth scanner, can be connected to the computer or connect to the Pad and mobile phone, as long as the above device has Bluetooth function, its connection process is a little more complicated. Plug in the Bluetooth adapter on the computer, the driver is installed, open the Bluetooth (Bluetooth program software on the screen), scan the device, at the same time, start the Bluetooth scanner (guarantee the status is Bluetooth transmission mode, generally the default), wait for the computer The device such as a mobile phone searches for a scanner, clicks on the confirmation, and the connection is successful, and the scan operation can be performed.
