2. What is a smart card?
A smart card also known as an integrated circuit Card as any credit card or id size card with embedded circuits that can process data.

3. Why use a Smart card Smart cards are very useful to any type of
organization that has data that needs to be stored
about an individual. They can be used for security
to identify and authenticate a user or employee.
Every FSU student and faculty member is issued
one of these smart cards when they come to FSU.
One main use of smart cards here at FSU is to
store electronic money which can be used to pay
For printing at public labs or buy snacks and
drinks at the vending machines across campus.

4. How does it work? Key Smart card circuit
VCC : Power supply input
RST : Either used itself (reset signal supplied from the interface device) or in combination with an internal reset control circuit (optional use by the card). If internal reset is implemented, the voltage supply on Vcc is mandatory.
CLK : Clocking or timing signal (not all cards use this functionality).
GND : Ground (reference voltage).
VPP : Programming voltage input (deprecated / optional use by the card).
I/O : Input or Output for serial data to the integrated circuit inside the card.
Remaining contact pins are usually used for card specific operations.
Note: This is not the layout of all smart cards, this is an example.

5. History Helmut grottrup
Helmut Grottrup invented the predecessor of the smart card. He invented the automated chip card in 1968 and patented it in This was first used in France for pay phones

6. Modern uses
Modern smart cards are now being used wirelessly for many things such as Subway entry or as credit cards. Smart cards are also being used more and more in the security industry for identification and authentication.

7. Security
Cryptographic smart cards are often used for single sign-on. Most advanced smart cards are equipped with specialized cryptographic hardware that let you use algorithms such as RSA and DSA on board. Today's cryptographic smart cards are also able to generate key pairs on board, to avoid the risk of having more than one copy of the key.
With new smart cards identification of people has become easier than ever. Updating a persons security clearance can be done with the swipe of a card, and authentication of a persons identity can also be done with a swipe of a card.

8. Disadvantages
Hackers can use new smart cards to re-write data on these cards if they are not encrypted. Like any other information if you can break into the storage you can re-write the information.
An example from the FSU card, if you could re-write the data on your smart card you could get free drinks, snacks or printing anywhere that the smart card is used for payment on campus.
