A smart card is a card that is embedded with a computer chip. This chip can either be a microprocessor chip or strictly a memory chip. Generally the cards are the size of a credit card, and look a lot like a credit card, however they do not have a magnetic stripe on the back. These cards were first developed in the 1970s and are now widely used around the world for managing and storing all sorts of information. How They Work The manufacturer starts with a basic base, usually a plastic card. Then they glue the microcontroller onto the card and seal it with a printed circuit. The nature of the controller and the circuit depends on the function of the card will be. There are many different types of Smart Cards. Integrated Circuit cards are the kinds of Smart Cards many people are familiar with, the term is ambiguous to define smart cards that have plastic bases that are the size of credit cards. Memory only cards are embedded with chips that have ROM (read only memory) memory types. Once the information is recorded onto the chip, it is only accessable through connection to its reader, and the information cannot be changed or manipulated. Julie Daniels Page #2 Some Smart Cards however are equipped with microprocessors. It is like having a mini-CPU right there on the card. These cards can contain ROM, PROM (Programmable read only memory), EPROM (erasable programmable read only memory), EEPROM (electrically erasable programmable read only memory) and/or RAM (random access memory). These cards not only store information, but the user can also add, erase, or change the data on the card. change the data on the card....
