In the world of retail there cannot be many more revolutionary products compared to handheld barcode scanner. The advantage of this kind of scanner is that it is so simple to use. Just point it on the barcode, press the trigger as well as the job is done. And since it is worked yourself anyone using one of these brilliant pieces of equipment is not as likely to make a mistake.

Strictly speaking handheld barcode scanners are connected to the computer by a cable. You will find handhelds which are connected up wirelessly. There isn't any cable restricting how long the scanner can be used from the computer; the sole limit is the range of the wireless signal. They could be small enough to fit right into a pocket. The purists usually do not class these scanners as handheld, instead they'll 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 most people will be using will utilise a couple of scanning technologies, the laser as well as 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 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 along the barcode.

LED is really a newer type of scanning technology and also the handheld barcode scanners incorporating it tend to be 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 considering using a handheld unit within their business is whether to stay with the conventional 1D type of scanner or perhaps the newer 2D units. The 2D scanners are getting to be more popular as they provide more, especially of course the ability to read the new 2D barcodes including data matrix. These barcodes can hold much more information than the 1D type can which obviously ensures they are attractive to use. However, the 2D handheld scanners do cost a lot more than the 1D units. Obviously if the business can manage with the capacity restrictions with the 1D barcode then there is no real need to upgrade. Of course the converse is also true and many more businesses are now turning to the higher specification units.
