QRScanner

QRScanner - Un générateur de QR/code-barres et une application Android pour scanner

QRScanner is also know as Qr Reader, QR Code Reader, offers all required features, which can fulfill any modern application. It’s easy to customize, you can use any format of code like 1D (Barcode, UPC, CODE_128), 2D (QR code) etc

QR 1D(Barcode, UPC, CODE_128)

Linear or 1D barcodes, like the UPC code commonly found on consumer goods, use a series of variable-width lines and spaces to encode data — what most people probably think of when they hear “barcode.” Linear barcodes hold just a few dozen characters, and generally get physically longer as more data is added. Because of this, users typically limit their barcodes to 8-15 characters

Barcode scanners read 1D barcodes horizontally. 1D laser barcode scanners are the most commonly used scanners, and typically come in a “gun” model. These scanners do not need to be in direct contact with the 1D barcode to work properly, but typically need to be within a range of 4 to 24 inches to scan.

1D barcodes are dependent on database connectivity to be meaningful. If you scan a UPC code, for instance, the characters in the barcode have to relate to an item in a pricing database to be useful. These barcode systems are a necessity for large retailers, and can help increase inventory accuracy and save time.

QR 2D(QR Code)

2D barcodes, like Data Matrix, QR Code or PDF417, use patterns of squares, hexagons, dots, and other shapes to encode data. Because of their structure, 2D barcodes can hold more data than 1D codes (up to 2000 characters), while still appearing physically smaller. The data is encoded based on both the vertical and horizontal arrangement of the pattern, thus it is read in two dimensions.

A 2D barcode scanner doesn’t just encode alphanumeric information. These codes can also contain images, website addresses, voice, and other types of binary data. That means you can make use of the information whether you are connected to a database or not. A large amount of information can travel with an item labeled with a 2D barcode scanner.

2D barcode scanners are typically used to read 2D barcodes, although some 2D barcodes, like the commonly-recognized QR code, can be read with certain smartphone apps. 2D barcode scanners can read from over 3 feet away and are available in the common “gun” style, as well as cordless, countertop, and mounted styles. Some 2D barcode scanners are also compatible with 1D barcodes, giving the user more flexibility in how they are used.
