In the world of retail there cannot be many more revolutionary products than the handheld barcode scanner. The advantage of this kind of scanner is that it is so simple to use. Just point it at the barcode, press the trigger and also the job is done. Also, since it is worked yourself anyone using one of these simple pieces of equipment is less likely to make a mistake.

Strictly speaking handheld barcode scanners are coupled to the computer by a cable. There are handhelds which are connected up wirelessly. There isn't any cable restricting how long 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 into a pocket. The purists don't class these scanners as handheld, instead they use the term "wireless barcode scanner." However, these scanners do offer the same 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 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 has a laser diode. The laser diode generates a dot which becomes the laser beam by being projected into a vibrating mirror. The beam of light 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 more durable. Also LED is more versatile in the form 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 stay with the conventional 1D type of scanner or even the newer 2D units. The 2D scanners are becoming more popular as they do offer more, especially needless to say the ability to read the new 2D barcodes including data matrix. These barcodes can hold much more information compared to 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 from the 1D barcode then there is no real have to upgrade. Of course the converse can often happen and many more businesses are now turning to the higher specification units.
