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

In fact handheld barcode scanners are attached to the computer by a cable. There are handhelds which are connected up wirelessly. There is no cable restricting what lengths the scanner can be utilized from the computer; the only limit is the array of the wireless signal. They can be small enough to fit in to a pocket. The purists usually 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 a couple of scanning technologies, the laser and the LED. Lasers remain 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 laser beam by being projected in to a vibrating mirror. The laser beam is then scanned across the barcode.

LED can be a newer type of scanning technology and the handheld barcode scanners incorporating it will be more durable. Also LED is much more versatile in the form 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 about using a handheld unit inside 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 needless to say the ability to read the new 2D barcodes including data matrix. These barcodes can take 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 using the capacity restrictions with the 1D barcode then there is no real must upgrade. Of course the converse is also true and many more businesses are now looking at the higher specification units.
