What is a smart card?

The standard definition of a a smart card, or

integrated circuit card (ICC), is any pocket sized card

with embedded integrated circuits.

OR

A smart card is a plastic card with a small, built

in microcomputer chip and integrated circuit

that can store and process a lot of data

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).


11/22

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.

SMART CARD READERS

(2)Dedicated terminalsUsually with a small screen, keypad, printer, often alsohave biometric devices such as thumb print scanner.

(1.)Computer based readersConnect through USB or COM (Serial)

ports

Memory-Based Smart Cards. capability

Microprocessor-based smart card. Based

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.


15/22

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


17/22

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 .

Security Mechanisms In Smart Cards

Password

Card holders protection

Cryptographic Security

Entity authentication

Biometric Security

Persons identification

A combination of one or more


19/22

Uses:-

Net surfing.

Electronic purse(debit/credit card).

Banking(ATM card).

Employee attendance.

Medical identification.

Identity card.

Driving licence.

Pan card.

Passport.

Payphones.

And many more apps..


20/22

Advantages:-

Faster and smarter.

Portability.

Flexibility(no need to carry separateATM,Debit,Credit card or DL,pan card etc.).

Highly secured.(deactivates on illegle use).

Gives its own network for internet surfing. Reliability (unaffected by electric and

magnetic field).


21/22

Disadvantages:-

COST AND AVAILABILITY

Expensive.

All readers can not read all types of smart

card(depends upon the smart card brand).
