Barcode decoders consist of sensors or receivers that convert barcode images into language or data that humans can understand. Everyone is familiar with the UPC barcode decoders at checkout lanes. Some of these are incorporated into countertops or other checkout isle systems. Others are hand-held, attached by cables to registers.
However, there are several other types of barcode image decoder devices. For instance, a portable, hand-held UPC code decoder works well to compile inventory data. Similar devices allow the quick entry of orders from barcode catalogs or track the movements of materials on factory floors. Beyond all these types of devices, however, there is also barcode decoder software that works with online barcode libraries to support online barcode decoders.
There are three main bar code sensing mechanisms:
1. Visible laser diode (VLD) is the most common type. These employ multiple laser beams focused together, along with a photo diode as a reflected image barcode converter.
2. Light emitting diode (LED) barcode readers are similar to those with VLDs.
3. Charged coupled device (CCD) types are a barcode scanner decoder with a CCD, like those in many cameras, scanners and other imaging devices.
Action Steps
The best contacts and resources to help you get it done
Choose from a variety of bar code decoders to find the one that best suits your needs
Some barcode decoders or scanners are only readers, while others are programmable and have memory capabilities for upload to computer systems. They also come in many shapes and sizes, and there isn't just one that will do the job for you. Take advantage of the variety by shopping barcode decoder sources that have large selections.
I recommend: CDW has a massive selection of both stationary and hand-held barcode devices at a full range of price points. Additionally, WorthData USA has some excellent data collection devices, including a portable scanner that comes along with a radio frequency (RF) terminal with a 3000' range. This will help you get data where you want it fast, without constantly walking across huge factory or warehouse floors.
Single out 2D barcode decoders in your search
The most common barcodes are 1D, in that they consist of series of black bars. So if you are doing an online search for 2D barcode decoders, make sure to single them out in your query. This will reduce the field of scanners dramatically. Two dimensional barcodes vary in type, from matrices that look like strips of dot or hexagon clusters to 2D sets of lines or bars.
I recommend: BarcodeDiscounters.com has a nice selection of 2D barcode scanners, including units specifically designed for the industrial sector. SSE Technologies carries similar products, so do some price comparisons.
Turn your computer into a barcode online decoder
Install barcode decoding software to your computer from online sources, and you can use your computer as both a 1D and 2D barcode decoder. There are also more limited online services that do not require a full download to your computer.
I recommend: DTK Software offers barcode reading software that integrates into document systems, Windows applications and much more. The software reads barcodes from digital images and bitmaps. There are many other sources of online and computer operated barcode image decoders, like dLSoft. The company carries decoders in three software types.
