• Plotters are used to print graphical output on paper. It interprets computer commands and makes line drawings on paper using multicolored automated pens.
For a magnetic stripe card to work, the service provider is required to swipe the card, the card then processes the information via an on-line system and will then authorise the card. A smart card works off-line and does not need to be processed on-line.
