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 that it is so simple to use. Just point it at the barcode, press the trigger and also the job is done. And since it is worked by hand anyone using one of these simple pieces of equipment is not as likely to make a mistake.
As it happens handheld barcode scanners are attached to the computer by a cable. There are handhelds which are connected up wirelessly. There is no cable restricting how long the scanner can be utilized from the computer; the only real 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'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 many people will be using will utilise one of two scanning technologies, the laser and the LED. Lasers continue to be the most popular, despite the introduction of LED scanning technology throughout 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 in to a vibrating mirror. The laser beam is then scanned over the barcode.
LED is a newer type of scanning technology and the handheld barcode scanners incorporating it will be more durable. Also LED is more versatile in the form of barcode it can read - technology-not only to scan horizontal bar codes 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 of using a handheld unit inside their business is whether to stay with the conventional 1D type of scanner or the newer 2D units. The 2D scanners are getting to be 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 compared to the 1D type can which obviously makes them attractive to use. However, the 2D handheld scanners do cost much more than the 1D units. Obviously if your business can manage with the capacity restrictions of the 1D barcode then there is no real need to upgrade. Of course the converse can often happen and many more businesses are now turning to the higher specification units.
