Barcode scanners and barcode readers are used to quickly, easily and accurately capture information represented in a bar code, usually to link it to data in a computer database.

Reading Technology

Laser barcode scanners
These are more expensive than CCD scanners or wand readers, but most clients select lasers for their ease of use and fast scanning ability. At one time laser scanners were less rugged than CCD scanners or wand readers, but the modern designs show no material difference in durability between wand and CCD

CCD scanners
are generally designed to read when held about half an inch from the bar code. This can make them less convenient to use than lasers in some applications, however there are longer range CCDs that have a 1-6" scanning distance.

Bar Code Wands
were at one time very popular for their exceptionally lightweight and lower cost. However, the drop in CCD prices makes cost less significant. Bar Code Wands are considered acceptable in environments such as libraries, where the barcode is on a flat, convenient work surface. In most other applications the wands have been replaced by lasers or CCDs.

Connection technology

Wedge Readers
are used to read bar coded information directly into a desktop computer. To install a wedge reader, the user disconnects the keyboard (after turning power off), and plugs the keyboard cable into the wedge reader. To the system unit, there is no difference between the user typing "123" and the user scanning a bar code printed with the number "123". Wedge readers are a very easy and flexible way to add bar code function to an existing system. They are fast being replaced by readers that connect through the USB port, or even by bluetooth.

Serial Connection

Usually for very application specific applications. Some careful set up required. Also, a special piece of software needs to be loaded and set to be always runnnig in the background. Not recommended, unless there is no alternative.

USB Connection

This is fast becoming the standard, though it may be replaced shortly by Bluetooth. It is possible to cascade barcode readers, but some special setup is required.

Bluetooth

Almost here. This will provide a fast and convenient connection. But a seperate charger will be required.

Cordless

The preferred method for connection. Very convenient, but a slight penalty on pricing.
