Barcode Technology - Codebar Barcode               Hide the description

Codebar is primarily used for medical purposes. It is a numeric code with some additional special characters

(0..9 and - $ : / . +). There are four different start and stop signs defined. These start and stop signs are used in our software as A, B , C and D. They are only valid at the beginning and the end of the code. They can be used to transport additional information.

Valid characters: 0123456789-$:/.+

Old format used in libraries and blood banks and on airbills (out of date, but still widely used in libraries)

Codebar is one of the many barcode formats currently in use.

A Barcode is a method of representing data in a visual, machine-readable form.

The barcode formats has two categories:

One-dimensional (1D) --- Barcodes represented data by varying the widths and spacings of parallel lines.

Two-dimensional (2D) --- Using rectangles, dots, hexagons and other geometric patterns to represented data.

Check digit:

Because Codabar is self-checking, most standards do not define a check digit.Some standards that use Codabar will define a check digit, but the algorithm is not universal. When all 16 symbols are possible, a simple modulo-16 checksum is used.[5] The values 10 through 19 are assigned to the symbols –$:/+.ABCD, respectively.

Human Readable:

Most barcodes display their corresponding values below them, which makes it possible to human read and manually  enter the barcode values into the equivalent system when the barcode label is worn out and cannot be read by the barcode scanner.

The Advantages of using barcodes:

Using Barcode system eliminates the possibility of human error. The error rate of manually entering data is
significantly higher than that of scan barcodes. Barcode scanning is fast and reliable, and it takes much less time than manual data entry. Especially when using a QR code, hundreds of characters can be read and entered into your system instantly.

When barcodes are used in management information systems, they can promote better decision-making. Because data is obtained quickly and accurately, you can quickly obtain a full range of information for the entire company or organization, so it is possible to make more informed decisions. Better decisions can ultimately save time and money.

Barcodes are cheap and user-friendly, providing an indispensable tool for tracking data from pricing to inventory. The end result of a comprehensive bar code system is reduced overhead.
