In the world of retail there cannot be many more revolutionary products compared to handheld barcode scanner. The beauty of this kind of scanner is that it is so simple to use. Just point it on the barcode, press the trigger and also the job is done. And because it is worked by hand anyone using one of these pieces of equipment is not as likely to make a mistake.

Strictly speaking handheld barcode scanners are coupled to the computer by a cable. There are handhelds which are connected up wirelessly. There's no cable restricting how far the scanner may be used from the computer; the only limit is the selection of the wireless signal. They can be small enough to fit in to a pocket. The purists don't class these scanners as handheld, instead they'll use the term "wireless barcode scanner." But these scanners do offer the same ease of use as the handheld variety.

cash register - The handheld scanners that most people will be using will utilise 1 of 2 scanning technologies, the laser and also the LED. Lasers continue being the most popular, despite the introduction of LED scanning technology during 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 right into a vibrating mirror. The laser beam is then scanned along the barcode.

LED can be a newer type of scanning technology as well as the handheld barcode scanners incorporating it will be more durable. Also LED is a lot more versatile in the type of barcode it can read - it can be used to scan horizontal barcode symbols as well as the more typical vertical ones. The sensor then accumulates the reflected light as well as the data is converted into ASCII text.

point of sale system - One decision that anyone thinking about using a handheld unit in their business is whether to stick to the conventional 1D type of scanner or the newer 2D units. The 2D scanners are becoming more popular as they do offer more, especially of course the ability to read the new 2D barcodes for example data matrix. These barcodes can hold much more information than the 1D type can which obviously makes them attractive to use. However, the 2D handheld scanners do cost far more than the 1D units. Obviously if your business can manage using the capacity restrictions of the 1D barcode then there is no real need to upgrade. Of course the converse is also true and many more businesses are now looking at the higher specification units.
