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

As it happens handheld barcode scanners are attached to the computer by a cable. You will find handhelds which are connected up wirelessly. There is no cable restricting how long the scanner can be used from the computer; the only real limit is the array of the wireless signal. They could be small enough to fit in to a pocket. The purists do not class these scanners as handheld, instead they'll 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 most people will be using will utilise a couple of scanning technologies, the laser and the LED. Lasers continue being the most popular, despite the introduction of LED scanning technology over the last few years.

With laser scanning technology the scanning unit contains 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 is really 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 kind of barcode it can read - you can use it to scan horizontal bar codes as well as the more typical vertical ones. The sensor then picks up 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 within 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 needless to say the ability to read the new 2D barcodes such as data matrix. These barcodes can take much more information compared to the 1D type can which obviously ensures they are attractive to use. However, the 2D handheld scanners do cost far more than the 1D units. Obviously if the business can manage using the capacity restrictions of the 1D barcode then there is no real have to upgrade. Of course the converse is also true and many more businesses are now turning to the higher specification units.
