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 Classic? 1K, MIFARE Classic? 4K, MIFARE? Ultralight, MIFARE? desfire, T5557, T5567, T5577, FM11RF08, ISSI S70, EM4100, EM4102, TK4100, TK4102, GEN2 6C, I-CODE-2, TI, HID..etc

Contactless IC Card

The Contactless card range consists of read-only low-frequency ID cards, MIFARE® cards, TypeB cards and CPU cards.
These cards are used for a variety of purposes e.g. identification and electronic wallet etc. As the transmission of power and data requires no physical contact with the card, users can truly enjoy the ease-of-use of contactless technology. No longer do users have to worry about damage during card contact with readers or stains on contact surfaces that may hinder data transmission.

Contactless IC Card Advantages:
Reliable
As there is no physical contact between card and reader, previous causes for failure e.g. bad reader/card
contacts are significantly minimized
Easy & fast operation
Eliminates the need to insert and retrieve cards from readers, therefore ensuring more user-friendliness.
This product can work within a 10cm distance from the card reader.
This product also works well regardless of orientation or card reader position.
Capable of Multiple Applications
Its special memory structure enables multiple applications to run on this card. It can also run on a variety of systems. Users can define their own code and access condition for each application respectively.
Excellent Authentication and Security
A unique serial number is assigned and written into each card during its manufacturing phase. This serial
number can never be changed after the card leaves the factory.
A mutual validation standard is adopted between card and reader, meaning, the reader needs to verify the
card and the card needs to verify the reader before any transmission can begin.

Contactless IC Card Uses :
Identification
Finance and electronic money
Public transportation
Smart building
Community logistics
Social security and related fields
