![]() ![]() By the year 2000, Data Monitor predicts that over 3 billion cards will be in circulation worldwide - with over 15% of the total in use in the United States and Canada.īy way of comparison, there are over 900 million credit cards in circulation today. Currently, 95% of these cards are issued in Europe, South America, and Asia. This year, almost 1 billion smart cards will be produced worldwide by several large manufacturers. The first smart card was developed in 1974, by independent inventor Roland Moreno. While the cards are comparable in price to chip cards, the card readers use non-standard protocols and are expensive. Today, these cards have no processor in them (although this is coming in the near future). Thus, this type of card is ideal for record keeping - for example medical files, driving records, or travel histories. But once written, the data cannot be changed or removed. Optical memory cards can store up to 4 MB of data. Optical memory cards look like a card with a piece of a CD glued on top - which is basically what they are. Memory cards are popular as high-security alternatives to mag stripe cards. Memory cards represent the bulk of the 600 million smart cards sold last year, primarily for pre-paid, disposable-card applications like pre-paid phone cards. Thus, they are dependent on the card reader (also known as the card-accepting device) for their processing and are suitable for uses where the card performs a fixed operation. IC memory cards can hold up to 1-4 KB of data, but have no processor on the card with which to manipulate that data.
