` Many cards we carry daily for different purposes,may it be magnetic stripe card or some other plastic cards........why carry too many cards if asingle card- SMART CARD can serve allpurposes!!!!

` A smart card is a card that is embedded with either amicroprocessor and a memory chip or only a memorychip with non-programmable logic. Themicroprocessor card can add, delete, and otherwisemanipulate information on the card, while a memory-chip card (for example, pre-paid phone cards) canonly undertake a pre-defined operation

` Advantages of Smart CardsCompared to magnetic stripe cards, smart cards have many advantages:

Smart cards can hold up to 32 KB of data while magnetic cards as seen earlier can hold only around 1000 bits. This allows the card-transaction participants(card company, acquiring bank, issuing bank, retailers etc.) to store a lot of additional information on the card.

Data on a smart card can be protected against unauthorized viewing. As aresult of this confidential data (P IN , Passwords) can be stored on a smart card.This means, merchants do not have to go online every time to authenticate atransaction.

A single smart card can house multiple applications. Just one card can beused as your license, passport, credit card, ATM card, ID Card etc.

Life of a smart card is longer.` Data stored on magnetic stripe cards can be easily read and modified by

someone with access to the right kind of equipment.

` RO MData stored in ROM cannot be modified, or can be modified onlyslowly or with difficulty, so it is mainly used todistribute firmware (software that is very closely tied tospecific hardware , and unlikely to need frequent updates).

` EEP RO Mdata stored in EEPROM is persistent, and is kept when power islost

` R AMdata stored in RAM is transient, and is lost as soon as power is

lost

` 256 bytes to 4KB RAM.` 8KB to 32KB ROM.` 1KB to 32KB EEPROM.` Crypto-coprocessors are optional.` 8-bit to 16-bit CPU. 8051 based designs are

common.

The price of a mid-level chip when produced in bulk isless than US$1.


12/20

` The terminal/PC sends commands to thecard (through the serial line).

` The card executes the command and

sends back the reply.` The terminal/PC cannot directly access

memory of the carddata in the card is protected from unauthorizedaccess via some password or needs biometricverification. This is what makes the card smart.


13/20

` Dedicated terminalsUsually with a small screen,keypad, printer, often alsohave biometric devices such asthumb print scanner.

Computer based readersConnect through USB orCOM (Serial) ports


14/20

` An important aspect to smart cards to preventunauthorized users from gaining access to informationcontained on the card.

` The advantage smart cards have over magnetic stripecards is that the smart card contains the computer chipwhich stores the password or P IN .

` the password is not sent over a communication lineto a computer system for verification, which caneasily be tapped.

` most important part of a smart card is the software

that provide the applications

` F uture of Smart CardsG iven the advantages of smart cards over magneticstripe cards, there can be no doubt that the future of smart cards is very bright. If the current trends are

anything to go by, the smart card market is set for exponential growth in the next few years.

Future for smart cards depends mainly on theintroduction of multi-application cards and overcoming

the simplistic mindset that smart cards are just amethod of making a payment.


18/20

` Hence smart cards can be used to increasesecurity, reliability, convenience and many other advantages.
