In the world of retail there can not 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 also the job is done. And since it is worked manually anyone using one of these simple pieces of equipment is less likely to make a mistake.
In fact handheld barcode scanners are connected to the computer by a cable. You will find handhelds which are connected up wirelessly. There is no cable restricting how long the scanner may 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 will use the term "wireless barcode scanner." However 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 a couple of scanning technologies, the laser and 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 has 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 the handheld barcode scanners incorporating it tend to be durable. Also LED is a lot more versatile in the kind 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 and also 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 stick to the conventional 1D type of scanner or perhaps the newer 2D units. The 2D scanners are becoming more popular as they offer more, especially of course 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 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 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.
