History : smart card Invention
In 1968 German electrical engineer Helmut
Grttrup and his colleague Jrgen Dethloff
invented the automated chip card.
receiving a patent in 1982, while working for
German company Giesecke & Devrient.
The first mass use of the cards was as a
Tlcarte for payment in French pay phones,
starting in 1983.

What does smart card have?
A smart card resembles a credit card in size andshape, but inside it is completely different. First ofall, it has an inside -- a normal credit card is a simple
piece of plastic. The inside of a smart card usuallycontains an embedded microprocessor.
The microprocessor is under a gold contact pad on
one side of the card.Smart cards are defined by the ISO 7816 standards.

Smarts cards may have up to 8 kilobytes of
RAM, 346 kilobytes ofROM, 256 kilobytes of
programmable ROM, and a 16-bit microprocessor.

How does a smart card works?
Smart Card Readers are also known as card programmers(because they can write to a card), card terminals, cardacceptance device (CAD) or an interface device (IFD).
Smart cards are portable data cards that must communicatewith another device to gain access to a display device. Cardscan be plugged into a reader, commonly referred to as a card
terminal, or they can operate using radio frequencies (RF).

When the smart card and the card reader come
into contact, each identifies itself to the other
by sending and receiving information. If themessages exchanged do not match, no further
processing takes place.

1. Contact smart card.
Contact smart cards have a contact area
comprised of several gold plated contact
pads(chip)
A contact smart card must be inserted in to a
smart card reader with a direct connection to
the conductive plates of the surface of the
smart card.

2. Contactless smart card.
Uses an inbuilt internal antenna forcommunication with the card reader.
It just requires a close proximity (10 cm.)to the
reader.
The antenna used in these use radio frequency to
communicate.

3.Microprocessor-based smart card
The microprocessor-based smart cards have greatermemory storage.
A microprocessor card, can add, delete and manipulateinformation in its memory on the card. Similar to acomputer, a microprocessor card has an input/outputport operating system and hard disk with built-in securityfeatures.
The microprocessor-based smart cards have=> 8-bit processor
=> 512 byte RAM
=> 16 byte ROM

4. MEMORY BASED SMART CARDS
used for applications in which the function of
the card is fixed.
Memory cards simply store data and can be
viewed as a small floppy disk with optional
security .
These cards are widely used as prepaid
phone cards .
