Well What Is It?

• Does this seem familiar

Well Smart cards are sorta like credit
cards Without all the problems.
Are you ever out shopping
Or buying gas
Or out to dinner
And think you are going to go crazy because your
credit card wont go through due to communication
problems?

What the heck does that mean?

• Well, credit cards need to access remote
  databases at the time of any transactions. Then
  using the information on the magnetic strip, they
  can receive information from the databases.
• Smart Cards on the other hand are embedded with
  chips that store the information right on the
  card. They look like a credit card, only without
  the magnetic strip.
• Some Smart cards contain only non-programmable
  data, however some are also equipped with a
  microprocessor that can add, delete, and change
  the information on the card.

Why Smart Cards?

• Smart cards are much more convenient than cards
  with remote-access magnetic strips since no
  communication lines are necessary.
• Since the information on smart cards is not
  stored at a remote database, the information is
  more secure and confidential.
• Smart cards are more durable and last longer than
  magnetic stripe cards before they wear out.
• Smart cards can be hybrid with magnetic
  stripes, allowing them to both secure
  confidential information and also access remote
  databases
• Smart cards can hold more than 17,000 times the
  amount of information as magnetic stripes.

There Are 3 Kinds Of Smart Cards On The Market
Today.

• Integrated Circuit Microprocessor Cards
• Integrated Circuit Memory Cards
• Optical Memory Cards

6
Integrated Circuit Microprocessor Cards

• 8 bit processor, 16KB read-only memory, 512 bytes
  random-access memory
• These cards can
• Hold money (gift cards)
• Secure access to networks (like in out laptops)
• Protect from cell phone fraud
• Protect from cable piracy (prevent illegal cable)

7
Optical Memory Cards

• Up to 4 MB of data but no internal processor.
• Since the data on the cards cannot be changed
  once programmed, these cards are normally used
  for storing information such as
• Medical files
• Traveling history
• Driving records
• Immigration green cards
• Military cargo manifests
