A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [1] Like a flatbed scanner, it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals. Additionally, nearly all barcode readers contain decoder circuitry ...
The application Barcode Scanner is an Android app, from the open-source project ZXing (short for Zebra Crossing ), that allows an Android device with imaging hardware (a built-in camera) to scan barcodes or 2D barcodes and retrieve the data encoded. [2] Information encoded often includes web addresses, geographical coordinates, and small pieces ...
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [5] [6] [7] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [8] the pattern of position detection was found and determined by applying the least-used ratio (1:1:3 ...
A barcode or bar code is a method of representing data in a visual, machine-readable form. Initially, barcodes represented data by varying the widths, spacings and sizes of parallel lines. These barcodes, now commonly referred to as linear or one-dimensional (1D), can be scanned by special optical scanners, called barcode readers, of which ...
Scandit. Scandit AG, commonly referred to as Scandit, is a Swiss technology company that provides smart data capture software. Their technology allows any smart device equipped with a camera to scan barcodes, IDs and text and to perform additional functions using augmented reality and advanced analytics. The company has more than 550 employees ...
Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images with embedded barcodes.
Image scanners are usually used in conjunction with a computer which controls the scanner and stores scans. Small portable scanners, either roller-fed or "glide-over" hand -operated, operated by batteries and with storage capability, are available for use away from a computer; stored scans can be transferred later.
Interface technology allowed the linking (usually via cables) of barcode-scanner hardware to other consoles. Games released for non-scanning consoles would employ the barcode scanner as a means to unlock secret content within the game or to add enhanced functionality.
