Smart Card ?
The first smart card was developed in 1974, by “Roland Moreno”
A smart card is a plastic card that is embedded with either a microprocessor or a memory chip.
These smarts cards have the mechanism for storing and/or processing information.
(IC) Microprocessor Cards.
Also called as "chip cards“
The current generation of chip cards has an 8- BIT processor, 16KB ROM, and 512 bytes of RAM
Applications :
stored value cards
affinity cards
These cards can provide services :
secure access to a network
cellular phones from fraud
IC memory cards
IC memory cards can hold up to 1-4 KB of data, but have no processor
also known as the card-accepting device
Applications like pre-paid phone cards and also popular as high-security alternatives to magnetic stripe cards.
Optical Memory Cards
Optical memory cards can store up to 4 MB of data. But once written, the data cannot be changed or removed
These cards have no processor in them (although this is coming in the near future)
This type of card is ideal for record keeping - for example medical files, driving records, or travel histories.
Conclusion
The characteristics of both contact / contact-less smart cards are the same with one difference that is the distance required by the contact-less smart cards
RAM is one of the major differences between the Intelligent tokens and smart cards
The use of smart cards will increase in the future especially the contact-less type and also the use of intelligent tokens.
