Barcode Wands

Barcode Wands is the first widely used types of barcode readers. How can a play wand barcode? On the tip of the wand you'll find a small LED (light emitting diode) and a receiver of the photo. The light is reflected in the code in the receiver. From the pattern of the signal reflection of the wand can determine the type and content of the barcode. Reading a bar code wand is a simple but requires some practice. There is no shutter button, basically, the staff is "always" when connecting to a PC. Then the user holds a pen and moves quickly from left to right to left on the bar code.

Barcode Scanner CCD

It is almost certain that most Current scanners are of the Charge Coupled Device (CCD) scan rate. A good barcode scanner CCD less easily exceed $ 100 a magic wand and sometimes even a laser scanner that costs two or three more times. A CCD scanner is like an "extended wand. Where sticks have only a light emitting diode and receiver, CCD scanners have a whole row of such elements. By activating the entire code scanner is illuminated and exposed to reception elements. Scanning bar codes with a CCD scanner is faster and more reliable than with a barcode wand.

Scanner laser bar code

Laser scanners have the name of a diode laser in the scanning head or "search engine" as is sometimes called. The beam is projected through a system of lenses and mirrors in the bar code, resulting in a visible red line or pattern of lines only. Laser scanners have two modes: They can be used on a stand and be automatically triggered if a bar code is held in front of scanner. This can be very useful as it keeps your hands free personal and is one of the real advantages of laser scanners. Outside the position of these devices using a toggle button similar to a CCD scanner to trigger the scanning process.

Barcode Imager

Two of Two-dimensional bar codes or area have gained much popularity in recent years. With a 2D bar code, you can encode up to 3,000 bytes of information a symbol of unique bar code, the size of a stamp. However, this progress comes with a major disadvantage: regular barcode scanners will not read these barcodes. To scan bar codes in the area, called barcode images are required. These scans basically functions as a digital camera, ie taking a picture of the barcode, decode and process the data encoded and transmitted to the host computer.

Connecting a bar code scanner to a computer

PCs still outnumber Macs by far, so it's no surprise that most scanners using an interface that only connects to the PC: A keyboard wedge. Basically, a keyboard emulation is a "Y" shaped cable that connects the scanner, the keyboard and the PC. All that the scanner sends the computer looks as if the user has typed at the keyboard. Drivers are not required, installation is a cinch.

For Macintosh computers or laptops that lack keyboard ports, a connection via USB is the only viable alternative.
