In the world of retail there can't be many more revolutionary products compared to handheld barcode scanner. The good thing about this kind of scanner is 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 manually anyone using one of these simple pieces of equipment is not as likely to make a mistake.
In fact handheld barcode scanners are attached 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 limit is the selection of the wireless signal. They may be small enough to fit into a pocket. The purists usually do not class these scanners as handheld, instead they use the term "wireless barcode scanner." But these scanners do offer the identical 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 as well as 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 includes 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 along the barcode.
LED is really a newer type of scanning technology and also the handheld barcode scanners incorporating it tend to be more durable. Also LED is more versatile in the form 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 sees 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 inside their business is whether to stick to the conventional 1D type of scanner or the newer 2D units. The 2D scanners have become more popular as they do offer more, especially needless to say the ability to read the new 2D barcodes for example data matrix. These barcodes can hold much more information compared to 1D type can which obviously means 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 with the 1D barcode then there is no real need to upgrade. Of course the converse can often happen and many more businesses are now embracing the higher specification units.
