magnetic stripe readers
Bar code scanners
A barcode reader, also known as a barcode scanner, is an electronic device capable of reading printed barcodes on different objects. It operates simply by pointing the light source which is a scanner at the black and white barcode. That sends an inscribed message to the computer it is linked to.
radio tag
A radio tag is the piece of hardwair that is detected through radio frequency identification by a device, that serves as a terminal, capable of detecting this tag using signals. It is similar to a sticker and is placed on objects that need tracking.
magnetic ink character recognition (MICR)
Magnetic ink character recognition is yet another form of character recognition. This process functions by a machine capable of reading a specific type of ink. The scanner is then able to process what it scanned into chracters. For well printed MICR documents, the "character not recognised" rate is usually less than 1% while the substitution rate of a character is in the order of 1 per 100,000 characters.
