A smart card is a credit-cardsized plastic card embeddedwith an integrated circuit chipthat makes it "smart".

This marriage between aconvenient plastic card and a

microprocessor allows animmense amount of information to be stored,accessed and processed eitheronline or offline.



Smart card contains both the data and the

means to process it, information can be processedto and from a network without changing the card’sdata.

Smart cards are portable, users can carry data

with them on the smart card rather than entrustingthat information on network storage or a backendserver where the information could be sold oraccessed by unknown persons.



A smart card can restrict the use of information to anauthorized person with a password.

However, if this information is to be transmitted by radiofrequency or telephone lines, additional protection is

necessary.

One form of protection is ciphering (scrambling data).Some smart cards are capable of ciphering and deciphering,so the stored information can be transmitted withoutcompromising confidentiality.

Smart cards can cipher into billions of foreign languagesand choose a different language at random every time theycommunicate.

This process ensures that only authenticated cards andcomputers are used and makes hacking or eavesdropping

virtually impossible.

Some smart cards have golden plates, contact pads, at onecorner of the card.

This type of smart cards are called Contact Smart Cards. Theplates are used to supply the necessary energy and tocommunicate via direct electrical contact with the reader.

Some smart cards do not have a contact pad on their surface.

The connection between the reader and the card is done via radiofrequency (RF).

They are having embedded antenna inside it. The reason issome smart cards can be read up to 1.5 meters away from thereader but some needs to be positioned a few millimeters from

the reader to be read accurately.



This type of smart cards, contains EEPROM(Electrically Erasable

Programmable Read-Only Memory), non-volatile memory. Because it is non-volatile when you remove the card from the reader, power is cut off, card storesthe data.

The data can be locked with a PIN (Personal Identification Number), yourpassword (3 to 8 digit).

Microprocessor cards, are more like the computers we use on our desktops.

They have RAM, ROM and EEPROM with a 8 or 16 bit microprocessor. InROM there is an operating system to manage the file system in EEPROM andrun desired functions in RAM.

The operating system is responsible for the security of the data in memorybecause the access conditions are controlled by the OS.



While any IC-embedded card may be called a smartcard, its distinguishing feature is its use for personalactivities.

For example, PC cards have the same characteristics asa smart card but they are used as peripheral devices suchas modems or game cartridges.

These PC cards are seldom called smart cards since theyare extension devices without personalization. In this

sense, a smart card is a processor card that allows personsto interact with others digitally to conduct transactions andother personal activities.



Worldwide smart card salescould reach 1.6 billion units in1998.

Western Europe accounts forabout 70% of the current smartcard uses.

However, most smart cardsissued today are memory cards(see Table) with limited

processing capabilities. Still,hundreds of millions of processor cards are already inuse today.

Phone cards have becomeubiquitous in Western Europe

and Asia where coin-operatedpublic phones are becomingnearly obsolete.

However, processor cards areprojected to be the fastestgrowing smart card uses by the

year 2000.



A smart card begins with a micro-controller produced bysemiconductor manufacturers such as Siemens, Motorolaand Thomson.

This integrated circuit chip is attached to an electronicmodule by inserting into a cavity on the module.

Then, terminals between the chip and the electronicmodule are interconnected. Finally, the chip-embeddedelectronic module is glued to a plastic card.

The global leader in card manufacturing isSchlumberger who sold about half of all smart cards inuse in 1997.

Smart cards were first developed as a payment method tosimplify small value transactions.

This has proven to be useful in Western Europe and Asiawhere public transportation and public phones are widelyused.

In North American, the popularity of checks, credit cards

and debit cards makes smart cards a less attractivealternative.

. In some countries, the increasing use of smart cards isalso leading to advancements in banking services and theacceptance of credit and debit cards by consumers.
