In the world of retail there can not be many more revolutionary products than the handheld barcode scanner. The good thing about this kind of scanner is 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 manually anyone using one of these pieces of equipment is not as likely to make a mistake.

In fact handheld barcode scanners are coupled to the computer by a cable. You will find handhelds which are connected up wirelessly. There isn't any cable restricting how far the scanner may be used from the computer; the sole limit is the selection of the wireless signal. They can be small enough to fit into a pocket. The purists do not class these scanners as handheld, instead they'll 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 a lot of people will be using will utilise 1 of 2 scanning technologies, the laser and 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 into 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 much more versatile in the kind of barcode it can read - you can use it 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 about using a handheld unit within their business is whether to stay with the conventional 1D type of scanner or even the newer 2D units. The 2D scanners are getting to be more popular as they do offer more, especially obviously the ability to read the new 2D barcodes including data matrix. These barcodes can take 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 using the capacity restrictions with the 1D barcode then there is no real need to upgrade. Of course the converse often happens and many more businesses are now embracing the higher specification units.
