Smart Cards / RFID Cards
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 to enable the transmission of data, commands and card status, hypothetically taking less time to authenticate versus contact smart cards. Both reader and card have an internal antenna that securely communicates with the other.
Various intergrated circuit card types available. Contact cards and Contactless cards.

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 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.
