A barcode reader is an electronic device that reads the barcode by means of a laser and emits the number shown by the barcode, not the image. Basically, it consists of the scanner itself (which reads the code using a laser), a decoder and a cable or Wi-Fi antenna that acts as an interface between the decoder and the terminal or computer.
The function of the scanner is to read the bar code symbol and provide an electrical output to the computer, corresponding to the bars and spaces in the bar code. However, it is the decoder that recognizes the bar code symbology, analyzes the content of the read bar code and transmits this data to the computer in a traditional data format. It has several means of connection: the most modern in order of appearance USB, bluetooth, wifi, the oldest serial port, even directly to the PS2 port of the keyboard through an adapter, when a barcode is passed through the scanner it is like if the barcode number had been typed on the keyboard.
A scanner may have the decoder built into the handle, or it may be a decoderless scanner that requires a separate box, called an interface or emulator. Decoderless scanners are also used when making connections to portable "batch" scanners and the decoding process is done through the terminal itself.
With this barcode reader it is ideal for counter sales or making databases and inventories faster. You do not need specialized computer programs or complicated installations since you only connect it via USB.
It has an indicator LED that turns on when detecting or recognizing a barcode and incorporates a buzzer (buzzer) which allows you to quickly identify if the codes are wrong or not or cannot be read. Its connection cable has a length of 1.9 m that allows you a wide range of mobility.
It can read different types of barcode: EAN128, Codabar, Industrial 2 of 5, Interleaved 2 of 5, Matrix 2 of 5, MSI, Chinese, etc. and its reading speed is 58 captures per second.
