A barcode scanner's primary purpose is to read barcode symbols and send an electrical signal to a computer through a decoder and connection (if the barcode scanner is not wireless). The decoder scans the barcode symbol, converts the data, and sends the information to the computer in readable format. Barcode scanners are highly advantageous to your business, especially if you're searching for a more effective and organized manner to run things.
Barcode
A barcode is a machine-readable visual pattern that encodes information. Barcodes are used for a number of purposes, including centralized registration of items, pricing, and stock levels in a computer software system.
Universal Product Code (UPC): A universal product code (UPC) is a code that is placed on the packaging of a retail product to aid in its identification. A UPC is made up of two parts: a machine-readable barcode (which looks like a sequence of black bars) and a unique 12-digit number beneath the barcode.
Barcode scanner
The lighting system, the sensor, and the decoder are generally the three components of a barcode scanner. A barcode scanner, in general, illuminates the black and white sections of a barcode with a red light, which is subsequently transformed into corresponding text.
How do they work?
In a word, a barcode is a means of encoding data into a visual pattern that can be read by a machine (those black lines and white spaces) (a barcode scanner).The mixture of black and white bars (also known as elements) symbolizes various text characters that follow a pre-determined barcode algorithm (more on the types of barcodes later). This pattern of black and white bars will be read by a barcode scanner and translated into a line of test that your retail point of sale system can understand.
A decoder is built within a barcode scanner, and it analyzes the picture data produced by the sensor before sending it to the output port. It connects to a host computer after scanning an image to send the recorded data. The decoder recognizes barcode symbols, converts bar and space information, and sends data to a computer in a format that we can understand. Data can also be dropped into Accel or Excel databases using the decoder. That information can be entered into inventory records or used to receive and distribute files using special application software. It eliminates the need for manual data collecting, lowering the risk of human mistake. It also speeds up processes like asset management, point-of-sale transaction monitoring, and tracking inventory.
Types of barcode
1-dimensional (1D) barcodes
1D barcodes are a series of black and white bars that may store information such as a product's kind, size, and color. The universal product codes on the top of a product's packaging contain 1D barcodes
(UPCs). They have 12 digits, however other 1D barcodes, like code 128, use both letters and digits. These characters assist the barcode scanner record data by determining the spacing between each black bar.
2-dimensional (2D) barcodes
Two-dimensional barcodes are more complicated than one-dimensional barcodes. Pricing, inventory levels, and even a picture of the thing can be included in addition to text. A wide number of barcode scanners can read 2D barcodes. They have a capacity of 7,089 characters. A 2D barcode has much less storage than a 1D barcode.
