In the world of retail there cannot be many more revolutionary products compared to the 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 the job is done. And because it is worked by hand anyone using one of these simple pieces of equipment is less likely to make a mistake.

Strictly speaking handheld barcode scanners are connected to the computer by a cable. You will find handhelds which are connected up wirelessly. There's no cable restricting how far the scanner can be used from the computer; the only real limit is the range 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 a lot of people will be using will utilise a couple of scanning technologies, the laser and also 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 has a laser diode. The laser diode generates a dot which becomes the beam of light by being projected into a vibrating mirror. The laser beam is then scanned across 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 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 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 inside their business is whether to stay with the conventional 1D type of scanner or even the newer 2D units. The 2D scanners are becoming more popular as they offer more, especially obviously the ability to read the new 2D barcodes including data matrix. These barcodes can take much more information than the 1D type can which obviously means 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 using the capacity restrictions from the 1D barcode then there is no real have to upgrade. Of course the converse is also true and many more businesses are now embracing the higher specification units.
