In the world of retail there can not be many more revolutionary products compared to handheld barcode scanner. The advantage of this kind of scanner is that it is so simple to use. Just point it on the barcode, press the trigger and also the job is done. Also, since it is worked manually anyone using one of these pieces of equipment is not as likely to make a mistake.
In fact handheld barcode scanners are connected to the computer by a cable. There are handhelds which are connected up wirelessly. There's no cable restricting how far the scanner can be utilized from the computer; the sole limit is the selection of the wireless signal. They could be small enough to fit in to a pocket. The purists don't 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 1 of 2 scanning technologies, the laser as well as the LED. Lasers continue to be the most popular, despite the introduction of LED scanning technology over the last few years.
With laser scanning technology the scanning unit includes a laser diode. The laser diode generates a dot which becomes the beam of light by being projected into a vibrating mirror. The beam of light is then scanned across the barcode.
LED can be a newer type of scanning technology as well as the handheld barcode scanners incorporating it tend to be more durable. Also LED is more versatile in the form of barcode it can read - you can use it to scan horizontal barcode symbols as well as the more typical vertical ones. The sensor then sees the reflected light and also the data is converted into ASCII text.
point of sale system - One decision that anyone thinking of using a handheld unit inside their business is whether to stick 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 hold much more information compared to 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 with the capacity restrictions of the 1D barcode then there is no real must upgrade. Of course the converse is also true and many more businesses are now looking at the higher specification units.
