How a Barcode Reader Works. There are currently four different types of barcode scanners available. Each uses a slightly different technology for reading and decoding a barcode. There are pen type readers (i.e. barcode wands), laser scanners, CCD readers and camera based readers. Pen type readers consist of a light source and a photo diode that are placed next to each other in the tip of a pen or wand. To read a barcode, you drag the tip of the pen across all the bars in a steady even motion.
