The barcode scanner is applied for commercial POS system. And barcode scanner is divided into CCD barcode scanner, hand-held laser barcode scanner and the omnidirectional laser barcode scanner.
CCD barcode scanner is taken imaging pattern. Its advantages are no shaft, motor, long life and cheap price. When choosing CCD scanner, the most significant parameters are depth of field and resolution.
Laser handheld barcode scanner is a single line scanner which uses laser diodes as light source. It is mainly rotating mirror type and tremble mirror type. Commercial enterprises pay attention to the scanning speed and resolution instead of the depth when choosing laser handheld scanner.
When the Depth of field increased, the resolution will be greatly reduced. Excellent hand-held laser scanner should be high scanning speed, fixed depth and high resolution.

Using 2D bar codes, which can contain much more data than a traditional linear 1D bar code, allows users to customize the data captured and the way it is stored. This increases the ability of organizations to achieve their specific goals and create a database catered to their needs. For example, a client can store serial numbers for labeling in a database to be reviewed at another time. Medication vendors need to be able to read bar codes wrapped around tiny vials or printed on paper — sometime reflective foil.

Recently, we will have our new bluetooth 2d barcode scanner.
