We have listed below the main Smart Cards classified as 'Memory Cards' containing only non-volatile memory storage components. They have no on-board 'processor'; they can only undertake pre-defined or fixed operations dictated by the card reader. They are still widely used as stored value for telephone cards, in cashless vending e-purse solutions, loyalty, access control, school meals, laundry, and car-parking. They have largely replaced magstripe technology in the last decade and excellent for applications in general needing data portability but less processing capability.
If price is a key consideration, then memory cards tend to be less expensive than microprocessor cards but compromising with less security and processing features. Some memory cards have built in security features such as PIN protection but are limited to a maximum of 256Kbit storage. Others types such as I²C bus have no security protection but allow higher data storage capacity up to 1Mbit.
