Handheld Barcode Scanner is one of the most recent innovation in making POS or point of sale scans as well as to instantly gain access to specific files in a database. So how exactly does a Handheld barcode scanner work? This contraption comes equipped with a light source, light sensor and a lens which is responsible for interpreting the optical impulses to electrical impulses. It reads the barcode image as the light flashes on it and transmits the interpretation to the output center, commonly a computer screen or a cash register.

Among the most common brands in the market for the Handheld Barcode Scanners nowadays are Symbol, Metrologic, Wasp, Adesso, TS, PSC, CCD, CK1, Intermec, Trakker, Datalogic, Standard and Informatics. Though there are a number of brands available, they come with different features for each piece. The weight alone vary, some weigh as little as 9 ounces while others weigh up to 3 pounds. Some are slim while others are more bulky, there are also some which are connected by USB ports and wires while others are wireless and are connected via Bluetooth. For Handheld Barcode Scanners which are wireless, the hand held scanner is powered by a battery; each fully charged battery can scan up to 20,000 scans or can stay on for up to 30 hours. The standard line or range is one hundred and sixty feet; although for some models, there is still room to be able to scan and store outside these lines for one to twelve inches away from the boundary by using the memory mode. For those models which are connected with wires to a station, these can normally extend for up to 5 feet which makes moving it around easier than that with a very short cord. These hand held scanners are now more usually featured with a plug and play feature via a USB plug; this will enable one to instantly connect the scanner to the port station without having to install it with a separate software.

If one is to consider purchasing one of these , there are a few factors to consider to be able to make a wise decision. They would have to first identify the purpose of its use for them to be able to make the right decision. The first thing to consider should be what type of bar code will be scanned; there are two types; the 1 Dimensional and the 2 Dimensional barcode. A one dimensional barcode is that which is most common; these come in a series of vertical bars of different densities thus forming a rectangle. However, for codes which require more information, these are the 2 Dimensional barcodes which looks quite different and may seem like a small pattern, sometimes come in boxed images. The orientation of how the barcode will be scanned is another factor; the most common Handheld Barcode Scanner is the one which has linear beams; this is only effective when the scanner has been positioned to be perpendicular to the barcode.

The other type is the omni Directional scanner; this is where the scanner is effective in scanning barcode regardless of the orientation of the barcode-may it be horizontal, diagonal or vertical, it will still be able to read and interpret the bars. If the scanner will be used in a specific station much like that of a check out counter, they can opt for the standard scanner which are wired and ported; however, for more versatile needs such as back room or inventory scans, the wireless version or the Bluetooth and memory mode featured scanners would be a better fit. Both the warranty and guarantee of the product will play an essential role in purchasing a scanner; if it will be used in a small scale purpose or business, an extended warranty or those up to 5 years or so may not be required; however for those Handheld Barcode Scanners which will be used in industrial environments and will require a huge number of scans and storage needs, those models with specified warranties which extend for long periods of time may be more essential.

Handheld barcode scanners are any scanners that are held with hands. Fixed mount Barcode Scanners which are attached to a counter, assembly line, or wall and aren’t operated by the user in a direct way would be the opposite of the handheld scanner. Most handheld barcode scanners have a design with a trigger and a grip similar to a handgun to activate the scanning operation. Some scanners are designed with a button on top instead of a trigger below and with a grip. However, Portable Data Collectors (PDTs) are also scanners that are better related to the handheld barcode scanners and these PDTs can either be totally mobile computers, with different operating systems or Pocket PC or else can have their inherent data collection software running which functions to attach important information such as quantity stamps and time to the barcodes scanned.

When searching for handheld barcode scanners, there are some important performance specifications you should consider before purchasing which are minimum distance from the target, PCS value, maximum barcode width, resolution, scan rate. The minimum distance is the distance the target can be away from the scanner and it is important for non or near-contact only. The contrast level between bars and background to be high enough for consistent readings is measured by PCS which stands for Print Contrast Signal. The “X” dimension sometimes refers also to the minimum resolution and it equals to narrowest space or bar in the barcode which can be used to determine the density of a barcode that is the number of characters per inch.

The scan rate refers to the number of scans per second that a barcode scanner can differentiate between. The choices of optical head include CCD/ LED or laser. Both LED and Laser scanning methods result in a digital signal that has be translated into computer-compatible or recognizable data. Using a certain algorithm, each bar coded message is identified and interpreted by the decoder, then the decoder either transmits that data directly to the host computer or utilizes that data for additional purposes. Any device inserted between the terminal that translates the digital signals into usable codes and the scanner is referred to the term “wedge”.

Other important parameters you should consider when specifying the handheld barcode scanners are software interfaces, user interface options, reading specifications, environmental operating conditions and other general features.
