Smart card contains
electronic memory, and possibly an embedded integrated circuit (IC).
Smart cards have two different types of interfaces-- the contact smart
card and the contactless smart card. Contactless smart cards only require
close proximity to a reader (typically within a few inches) to enable
the transmission of data, commands and card status, hypothetically taking
less time to authenticate vs. contact smart cards. Both reader and card
have an internal antenna that securely communicates with the other.
Contact card
Contact smart cards must be inserted into a smart-card reader. The reader
makes contact with the card module electrical connectors that transfer
data to and from the chip. This physical contact permits the transmission
of data, commands and card status.
Contactless Card
Contactless smart cards, an intelligent token, is a credit card sized
plastic card embedded with an integrated circuit chip. It provides not
only memory capacity, but computational capability as well.

The self-containment
of smart card makes it resistant to attack as it does not need
to depend upon potentially vulnerable external resources.
Because of
this characteristic, smart cards are often used in different applications
which require strong security protection and authentication.

RFID Card
| Radio
frequency identification (RFID) is a generic term that is used to
describe a system that transmits the identity (in the form of a
unique serial number) of an object or person wirelessly, using radio
waves. |
|
| A
RFID system consists of an antenna and a transceiver , which read
the radio frequency and transfer the information to a processing
device , and a transponder , or tag, which is an integrated circuit
containing the radio frequency circuitry and information to be transmitted.

Mifare Card
Mifare card is
a type of RFID. Philips has developed Mifare MC1 1C S50, Mifare MC1
1C S70 to be used in contactless smart card according to ISO/IEC14443A.
|
The Mifare
system is designed for optimal user convenience.
The high
data transmission rate allows transactions to be handled less
than 100ms.
