What’s a barcode scanner?
Noticing a barcode scanner pretty much everywhere you go isn’t uncommon. It is typically seen in retail outlets or areas where individuals buy things. A barcode reader is also another term for it. It is a system that works electronically in reading printed barcodes. It evaluates the barcode’s image data through its decoder. That is generally why the cashiers who handle your purchase will just point it toward the barcode and it will reflect in the computer all the data the scanner can identify.
What are the different types of barcode scanners?
There are differing kinds of scanners. They differ in use, function, and actual appearance. The most prevalent one which you see almost everywhere is the hand held one, that has a trigger button for switching on to process the information from the barcode. There are also pen scanners you can simply swipe. They’re, of course, pen-shaped.
The stationary scanner, in keeping with its name, isn’t portable and is affixed to a table or wall. You can commonly discover these kinds in supermarkets and grocery stores. You will also find fixed position scanners, which are utilized by large industries like a barcode reader employed for shipping and quality management.

The types of scanners used will also vary depending on the kind of technology that is currently being employed to read barcodes. There are various types. The preferred ones are those that use laser beams for a light source. Pen-type readers, however, use photodiodes which ascertain the amount of light being reflected from the barcode.

Barcode scanners may be hooked up through an RS-232 serial interface and keyboard wedges. However just recently, USB connectors are also being employed given that this is the most convenient for end users. Even wireless connection is possible.
