What is smart card?
Standard credit card-sized with microchip embedded on it.
Any pocket-sized card with embedded integrated circuits.
Can hold up to 32,000 bytes.
Follow the MOORE’s law.
On a fundamental level, microprocessor cards are similar to desktop computers.
EVOLUTION OF SMART CARDS
HISTORY
1950-Used by diners club in 1950 as a plastic card
1968- German inventors patent combination of plastic cards with micro chips.
1970- Japan patent different version.
1974- Roland Moreno invents integrated chip card and patents it in France.
1977- Motorola produces first smart card microchip.
1979- Motorola develops first single chip microcontroller for bank in France.
1982- ATM cards with smart chips tested and smart chips placed on telephone cards.
1991- AT&T declared its contactless smart card.
1992- Germany uses smart card for health care.
1996- First university campus deployment of chip cards.
CURRENT TRENDS
Latest super smart cards have keypads, LCD displays, battery and math co-processors for performing complex encryption algorithms.
TECHNOLOGICAL FEATURES
256 bytes to 4KB RAM.
8KB to 32KB ROM.
1KB to 32KB EEPROM.
Crypto-coprocessors (implementing 3DES, RSA etc., in hardware) are optional.
8-bit to 16-bit CPU. 8051 based designs are common.
Length=4.96mm
Breadth=4.28mm
Chip area=21.33mm2
COS
Smart Cards
Processor cards (and therefore memory too)
Credit card size
With or without contacts.
Cards have an operating system too.
The OS provides
A standard way of interchanging information
An interpretation of the commands and data.
Cards must interface to a computer or terminal through a standard card reader.
FUTURE OF THE SMART CARD
I believe smart cards are the wave of the future for consumer use, commercial use and internal network security. Europe already has a head start on the U.S., as smart cards are in much wider use there.
With this technology identity theft and credit card fraud can be controlled to a great extent. Further it will give a fillip to the Internet commerce. It will be no exaggeration to predict that the future belongs to contact less smart card supporting multiple applications.
