In the world of retail there cannot be many more revolutionary products compared to the handheld barcode scanner. The advantage of this kind of scanner is it is so simple to use. Just point it on the barcode, press the trigger as well as the job is done. Also, since it is worked by hand anyone using one of these brilliant pieces of equipment is more unlikely to make a mistake.
Strictly speaking handheld barcode scanners are attached to the computer by a cable. You will find handhelds which are connected up wirelessly. There's no cable restricting what lengths the scanner can be utilized from the computer; the only limit is the range of the wireless signal. They could be small enough to fit right into a pocket. The purists do not class these scanners as handheld, instead they use the term "wireless barcode scanner." But these scanners do offer the same ease of use as the handheld variety.
cash register - The handheld scanners that a lot of people will be using will utilise 1 of 2 scanning technologies, the laser and also the LED. Lasers remain 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 laser beam by being projected in to a vibrating mirror. The beam of light is then scanned over the barcode.
LED is really 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 type of barcode it can read - it can be used to scan horizontal bar codes as well as the more typical vertical ones. The sensor then sees the reflected light and the data is converted into ASCII text.
point of sale system - One decision that anyone thinking of using a handheld unit within their business is whether to stay with the conventional 1D type of scanner or the newer 2D units. The 2D scanners have become more popular as they offer more, especially obviously 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 a lot more than the 1D units. Obviously if the business can manage with all the capacity restrictions from the 1D barcode then there is no real need to upgrade. Of course the converse is also true and many more businesses are now embracing the higher specification units.
