Scanner Definition - Tech Terms
Scanner: A scanner is an input device that scans documents such as photographs and pages of text. When a document is scanned, it is converted into a digital format. This creates an electronic version of the document that can be viewed and edited on a computer.
How Does Barcode Scanning Technology Work?
Barcode technology works of off a principle called symbology. Symbology at its basic form is what defines the barcode; it determines the mapping and interpretation of the encoded information or data. This encoding allows the scanning device to know when a digit or character starts and when it stops, similar to a binary representation. We recognize barcodes as an array of parallel lines alternating between white and black lines. Barcode scanning technology provides a simple and inexpensive method of recording data or information in a number of applications.
What is the laser used to read barcodes?
The scanners, or lasers, used to read the barcodes measures the light reflected form the linear barcode technology and can distinguish between the white and black lines. Calibration of the laser and system needs to be done to ensure the proper interpretation of the code itself.
How are barcodes arranged?
The symbologies of the barcode technology can be arranged or mapped in a variety of ways. A continuous symbology is marked by the characters beginning with a black line and ending with a white line or space, while discreet symbologies have characters encoded as a black line, a space, and then another black line. This takes care of the characters and how each individual number or letter is read. The lines of a barcode also have variances in encoding the widths of the lines. Some barcode technology systems use two separate widths to determine the character while others use multiple width lines. The use of any of these encoding styles depends, of course, on the application for which the barcode technology is being used.
How do you read barcodes?
In order to read the data of barcode technology it needs to be scanned by a laser and then interpreted. The scanners, or lasers, used to read the barcodes measures the light reflected form the linear barcode technology and can distinguish between the white and black lines. Calibration of the laser and system needs to be done to ensure the proper interpretation of the code itself. This has to do with whether it is a continuous or discreet symbology, 1D or 2D images, and whether it uses two width or multiple width lines. The most common lasers used are helium neon lasers due to their low energy consumption and efficiency.
What is symbology in barcodes?
Symbology at its basic form is what defines the barcode; it determines the mapping and interpretation of the encoded information or data. This encoding allows the scanning device to know when a digit or character starts and when it stops, similar to a binary representation.

Why do warehouses need to be manually scanned?
In a warehouse, manual screening of inventory helps to keep track of stock. But this is time taking and labor-intensive. Sometimes employees have to climb great heights to scan products, and a fall can be deadly. To solve this problem, a few logistics companies have deployed drones equipped with barcode scanners and obstacle avoidance sensors that can fly through each aisle of the warehouse. These can scan hundreds of barcodes within minutes!

The decoder recognises the barcode symbols, translates the bar and space content, and transmits the data to a computer in such a format that we can read. The decoder can also drop data into Accel or Excel databases.
Why are barcodes important?
These barcodes are significant for accurate inventory management. For example, the barcode seen on the tag of apparel in a retail store will have some black and white spaces with a product number, which is detected and scanned by a computer.
How do barcode readers work?
To read a barcode, the person holding the pen must move the tip of it across the bars at a relatively uniform speed. The photodiode measures the intensity of the light reflected back from the light source as the tip crosses each bar and space in the printed code. The photodiode generates a waveform that is used to measure the widths of the bars and spaces in the barcode. Dark bars in the barcode absorb light and white spaces reflect light so that the voltage waveform generated by the photodiode is a representation of the bar and space pattern in the barcode. This waveform is decoded by the scanner in a manner similar to the way Morse code dots and dashes are decoded.
What is the circuitry of a barcode reader?
Additionally, nearly all barcode readers contain decoder circuitry that can analyze the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.
What is the difference between a CCD reader and a laser scanner?

What would happen if retailers put barcodes on receipts?
If retailers put barcodes on receipts that allowed downloading an electronic copy or encoded the entire receipt in a 2D barcode, consumers could easily import data into personal finance, property inventory, and grocery management software. Receipts scanned on a scanner could be automatically identified and associated with the appropriate entries in finance and property inventory software.
How does a laser barcode scanner work?
A laser barcode scanner uses laser beams to illuminate the barcode so it can be read. The laser shoots a beam of light back and forth across the barcode and the photodiode in the laser scanner interprets the code. These scanners offer accuracy and high precision in reading the code.
Why are laser scanners dangerous?
Laser scanners, because of their internal moving parts, are less resistant to wear and tear and are susceptible to failure or damage .
