Smart Cards & Contactless Credit Cards available in Australia
Smart cards are the newest innovation in credit card security. These cards contain an embedded integrated circuit chip that is either a secure micro controller or a device with internal memory. By using direct contact or remote contactless radio frequency the card interfaces with a reader whenever you make a transaction. These cards are able to store significant amounts of information and carry out certain functions like encryption and mutual authentication. They can even interact in an intelligent fashion with the smart card reader.
Technology of smart cards
Smart cards conform to international standards, ISO/IEC 7816 and ISO/IEC 14443. They are available in many forms cards, fobs, and SIMS (subscriber identification modules) in GSM mobile phones, and USB tokens.
Contact or contactless:
- Contact cards need to be inserted or swiped in a smart card reader that has a direct connection to a conductive contact plate on the surface of the cards. These physical contact spots transmit the commands, data, and card status.
- Contactless cards only need to be close to the reader. The card and the reader both have antennae and communicate through radio frequencies. The range is about one -half to three inches making them good choices for things that need a fast card interface.

- The memory chip is similar to a floppy disk with added security. They are less expensive and have a less security control then micro controller chips.
- Micro controller chips have the ability to delete, add, and manipulate the data in its memory. It works like a mini computer that has an input and output port, an operating system, and a hard disk.
