What is a barcode?
A Barcode is an encoded set of lines and spaces of different widths that can be scanned and interpreted into numbers to identify a product. There are 2 types of barcodes: Linear and Data Matrix
Also known as a 1D Barcode it is a machine readable code consisting of a series of bars and spaces printed in defined ratios. Barcode symbology is essentially alphabets in which different widths of bars and spaces are combined to form characters and, ultimately, a message. Because there are many ways to arrange these bars and spaces, numerous symbologies are possible.
Data Matrix or 2D barcodes
A Data Matrix code, also known as a 2D barcode or simply a 2D code, is a two-dimensional way of representing information. It is similar to a linear barcode, but has more data representation capability, consisting of black and white square modules arranged in either a square or rectangular pattern. The information to be encoded can be text or raw data. The length of the encoded data depends on the symbol dimension used. Error correction codes are added to increase symbol strength: even if they are partially damaged, they can still be read. A Data Matrix symbol can store up to 2,335 alphanumeric characters. Every Data Matrix is composed of at least two finder patterns or handles and two syncs. Handles are two perpendicular lines, coloured the same way as 1 module, while syncs are like handles with the difference that they are made of alternating black and white modules. Handles achieve a good alignment with the symbol, while syncs sample modules correctly. If the matrix dimension grows, more syncs and handles are added up to 8 both horizontally and vertically. Symbol sizes vary from 8×8 to 144×144
Types of Barcode Scanners
Handheld scanners are best used in applications where the user is required to scan items of varying shapes or sizes, or may be at a distance from the operator, such as pallet stored on the top of a warehouse rack.
This type of scanner is connected directly to a defined workstation, using different cable combinations. USB is now the most popular, but other options are available such as PS/2, AT/XT, RS232 etc.
Cordless scanners allow the user to roam up to a 50 feet radius, by transmitting the scanned information to its cradle, via Bluetooth or Wireless, which is in turn connected directly to the defined workstation. The VisionID range of Handheld Scanners are an outstanding choice for Retail, Healthcare or Industrial environments.
Wall or table-mounted scanners that the barcode is passed under or beside. These are commonly found at the checkout counters of supermarkets and other retailers. Ideal for small retail operations and institutional organisations requiring dependable data entry. The omni-directional scan pattern reads the barcode regardless of orientation, eliminating the need to precisely align products to the scanner. Advanced software algorithms reconstruct poorly printed and damaged codes, further increasing performance and speeding customers through the point of sale.
Fixed Position scanners are typically used in applications where accurate, unattended automated data entry is required, such as tracking items throughout a manufacturing line, or machine-sortation of packages along a conveyor belt. Fixed Position scanners are available in short or long working distances for greater flexibility. Typically, omni-directional or rastering style scanners are used, enabling items to pass and to be read without precise positioning of the barcodes, resulting in accurate first-pass scans.
