In the world of retail there cannot be many more revolutionary products compared to the handheld barcode scanner. The advantage of this kind of scanner is that it is so simple to use. Just point it at the barcode, press the trigger as well as the job is done. Also, since it is worked yourself anyone using one of these pieces of equipment is more unlikely to make a mistake.

Strictly speaking handheld barcode scanners are connected to the computer by a cable. There are handhelds which are connected up wirelessly. There isn't any cable restricting how far the scanner can be used from the computer; the only limit is the selection of the wireless signal. They can be small enough to fit into a pocket. The purists don't class these scanners as handheld, instead they'll use the term "wireless barcode scanner." However these scanners do offer the same ease of use as the handheld variety.

cash register - The handheld scanners that many people will be using will utilise a couple of scanning technologies, the laser and the LED. Lasers remain the most popular, despite the introduction of LED scanning technology over the last few years.

With laser scanning technology the scanning unit has a laser diode. The laser diode generates a dot which becomes the laser beam by being projected into a vibrating mirror. The laser beam is then scanned along the barcode.

LED is a newer type of scanning technology and also the handheld barcode scanners incorporating it tend to be durable. Also LED is more versatile in the type of barcode it can read - technology-not only to scan horizontal barcode symbols as well as the more typical vertical ones. The sensor then accumulates the reflected light and also the data is converted into ASCII text.

point of sale system - One decision that anyone thinking about using a handheld unit within their business is whether to stick to the conventional 1D type of scanner or even the newer 2D units. The 2D scanners have become more popular as they offer more, especially needless to say the ability to read the new 2D barcodes including data matrix. These barcodes holds much more information compared to the 1D type can which obviously ensures they are attractive to use. However, the 2D handheld scanners do cost much more than the 1D units. Obviously if the business can manage with the capacity restrictions from the 1D barcode then there is no real have to upgrade. Of course the converse often happens and many more businesses are now embracing the higher specification units.
