Knowledge Of Contactless IC Card



     A contactless smart card is a card in which the chip communicates with the card reader through an induction technology similar to that of an RFID (at data rates of 106 to 848 kbit/s). These cards require only close proximity to an antenna to complete a transaction. They are often used when transactions must be processed quickly or hands-free, such as on mass transit systems, where a smart card can be used without even removing it from a wallet.

     The standard for contactless smart card communications is ISO/IEC 14443. It defines two types of contactless cards ("A" and "B") and allows for communications at distances up to 10 cm. There had been proposals for ISO/IEC 14443 types C, D, E, F and G that have been rejected by the International Organization for Standardization. An alternative standard for contactless smart cards is ISO/IEC 15693, which allows communications at distances up to 50cm.

     Examples of widely used contactless smart cards are Taiwan's EasyCard, Hong Kong's Octopus card, Shanghai's Public Transportation Card, South Korea's T-money (bus, subway, taxi), London's Oyster card, Beijing's Municipal Administration and Communications Card, Japan Rail's Suica Card, which predate the ISO/IEC 14443 standard. The following tables list smart cards used for public transportation and other electronic purse applications. First Data delivers Contactless Credit and Debit cards for its customers.

     A related contactless technology is RFID (radio frequency identification). In certain cases, it can be used for applications similar to those of contactless smart cards, such as for electronic toll collection. RFID devices usually do not include writeable memory or microcontroller processing capability as contactless smart cards often do.

There are dual-interface cards that implement contactless and contact interfaces on a single card with some shared storage and processing. An example is Porto's multi-application transport card, called Andante, that uses a chip in contact and contactless (ISO/IEC 14443 type B) mode.

     Like smart cards with contacts, contactless cards do not have a battery. Instead, they use a built-in inductor, using the principle of resonant inductive coupling, to capture some of the incident electromagnetic signal, rectify it, and use it to power the card's electronics.

     Commonly used in contactless IC card chip is: NXP(Philips) mifare 1 S50, mifare 1 S70, mifare ultralight, mifare desfire, T5557, T5567, T5577, FM11RF08, ISSI S70, EM4100, EM4102, TK4100, TK4102, GEN2 6C, I-CODE-2, TI, HID..etc
