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 on the barcode, press the trigger and the job is done. Also, since it is worked yourself anyone using one of these pieces of equipment is not as likely to make a mistake.
As it happens handheld barcode scanners are connected to the computer by a cable. You can find handhelds which are connected up wirelessly. There isn't any cable restricting how far the scanner can be used from the computer; the only limit is the range 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 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 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 laser beam by being projected right into a vibrating mirror. The beam of light is then scanned along the barcode.
LED can be a newer type of scanning technology and 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 - you can use it 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 thinking of using a handheld unit inside their business is whether to stick with the conventional 1D type of scanner or perhaps the newer 2D units. The 2D scanners are getting to be more popular as they do offer more, especially of course the ability to read the new 2D barcodes for example data matrix. These barcodes can hold 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 in case your business can manage with all the capacity restrictions from the 1D barcode then there is no real must upgrade. Of course the converse often happens and many more businesses are now turning to the higher specification units.
