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.
Choose from a variety of bar code decoders to find the one that best suits your needsSome 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.
Single out 2D barcode decoders in your searchThe 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.
Turn your computer into a barcode online decoderInstall 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.
- For a compact design, look for a pen or wand barcode decoder.
