Czytniki kart magnetycznych
A magnetic stripe reader, also called a magstripe reader, is a hardware device that reads the information encoded in the magnetic stripe located on the back of a plastic badge. Magnetic stripe readers can be read by a computer program through a serial port , USB connection, or keyboard wedge , and are generally categorized by the way they read a badge. For instance, insertion readers require that the badge be inserted into the reader and then pulled out. Swipe readers require that the badge pass completely through the reader.
