In the world of retail there can't be many more revolutionary products compared to handheld barcode scanner. The advantage of this kind of scanner is it is so simple to use. Just point it at the barcode, press the trigger and also the job is done. Also, since it is worked by hand anyone using one of these simple pieces of equipment is not as likely to make a mistake.

Strictly speaking handheld barcode scanners are coupled to the computer by a cable. You will find handhelds which are connected up wirelessly. There's no cable restricting how long the scanner can be used from the computer; the sole limit is the range of the wireless signal. They could be small enough to fit into a pocket. The purists usually do not class these scanners as handheld, instead they will use the term "wireless barcode scanner." However, these scanners do offer exactly the same ease of use as the handheld variety.

cash register - The handheld scanners that many people will be using will utilise one of two scanning technologies, the laser and also the LED. Lasers continue being the most popular, despite the introduction of LED scanning technology throughout 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 beam of light is then scanned over the barcode.

LED is 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 bar codes as well as the more typical vertical ones. The sensor then sees the reflected light as well as the data is converted into ASCII text.

point of sale system - One decision that anyone considering using a handheld unit in their business is whether to stick to the conventional 1D type of scanner or perhaps the newer 2D units. The 2D scanners have become more popular as they provide more, especially obviously the ability to read the new 2D barcodes for example data matrix. These barcodes holds much more information than the 1D type can which obviously ensures they are attractive to use. However, the 2D handheld scanners do cost a lot more than the 1D units. Obviously if the business can manage with all 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 turning to the higher specification units.
