In the world of retail there cannot be many more revolutionary products than the handheld barcode scanner. The beauty of this kind of scanner is it is so simple to use. Just point it in the barcode, press the trigger and also the job is done. Also, since it is worked manually anyone using one of these simple pieces of equipment is more unlikely to make a mistake.

As it happens handheld barcode scanners are connected to the computer by a cable. There are handhelds which are connected up wirelessly. There's no cable restricting how far the scanner can be used from the computer; the sole limit is the range 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 will 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 a lot of people will be using will utilise one of two scanning technologies, the laser and also the LED. Lasers remain the most popular, despite the introduction of LED scanning technology during the last few years.

With laser scanning technology the scanning unit contains a laser diode. The laser diode generates a dot which becomes the beam of light by being projected right into a vibrating mirror. The laser beam is then scanned across the barcode.

LED can be a newer type of scanning technology and also the handheld barcode scanners incorporating it will be more durable. Also LED is much 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 of using a handheld unit within their business is whether to stick with the conventional 1D type of scanner or even the newer 2D units. The 2D scanners are getting to be more popular as they do offer more, especially obviously the ability to read the new 2D barcodes including data matrix. These barcodes can hold much more information compared to the 1D type can which obviously makes them attractive to use. However, the 2D handheld scanners do cost much more than the 1D units. Obviously in case your business can manage with the capacity restrictions of the 1D barcode then there is no real need to upgrade. Of course the converse often happens and many more businesses are now looking at the higher specification units.
