In the world of retail there cannot be many more revolutionary products compared to the handheld barcode scanner. The good thing about this kind of scanner is it is so simple to use. Just point it in the barcode, press the trigger and the job is done. Also, since it is worked by hand anyone using one of these simple pieces of equipment is less likely to make a mistake.
As it happens handheld barcode scanners are coupled to the computer by a cable. There are handhelds which are connected up wirelessly. There is no cable restricting what lengths the scanner may be used from the computer; the only real limit is the selection of the wireless signal. They may be small enough to fit right into a pocket. The purists usually 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 also the LED. Lasers continue being the most popular, despite the introduction of LED scanning technology throughout the last few years.
With laser scanning technology the scanning unit contains a laser diode. The laser diode generates a dot which becomes the beam of light by being projected right into a vibrating mirror. The laser beam is then scanned over 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 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 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 stick 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 for example data matrix. These barcodes holds 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 in case your business can manage with the capacity restrictions from the 1D barcode then there is no real have to upgrade. Of course the converse can often happen and many more businesses are now embracing the higher specification units.
