CONTACTLESS SMART CARD Betty Yu

What is contactless smart card? A contactless smart card is a contactless MHz credential whose dimensions are credit-card size. Its embedded integrated circuits can store and sometimes process data and communicate with a terminal via radio waves. There are two broad categories of contactless smart cards. Memory cards contain non-volatile memory storage components, and perhaps some specific security logic. Contactless smart cards do contain read-only RFID called CSN (Card Serial Number) or UID, and a re-writeable smart card microchip that can be transcribed via radio waves.

Characteristics Dimensions are normally credit card size. Contains a security system which is different for every brand tamper-resistant properties (e.g. a secure cryptoprocessor, secure file system, human-readable features) and is capable of providing security services (e.g. confidentiality of information in the memory). Asset managed by way of a various central administration systems, or applications, which receive or sometimes interchanges information and configuration settings with the card. The latter includes card hotlisting, updates for application data. Card data is transferred via radio waves to the central administration system through card read write reader devices, such as access control mullion readers, ticket readers, ATMs, USB connected desktop readers or all devices embedding a contactless reader technology like printers, Time & attendance terminals, parking, lifts, point of sales, car sharing, etc.

Reader Contactless smart card readers use radio waves to communicate with, and both read and write data on a smart card. When used for electronic payment, they are commonly located near PIN pads, cash registers and other places of payment. When the readers are used for public transit they are commonly located on fare boxes, ticket machines, turnstiles, and station platforms as a standalone unit. When used for security, readers are usually located to the side of an entry door.

The Faraday Cage In order to understand everything that is being done around RFID (Radio Frequency Identification) protection, it's important to understand the principle that emerged in the early 1800s, when a physicist named Michael Faraday invented what is called the "Faraday cage." The Faraday cage works on the principle of manipulating radio waves and electromagnetic fields. By screening out electromagnetic radiation and blocking certain kinds of waves, a Faraday cage can either keep transmissions inside of a particular space, or keep them out of an internal area.

Benefit Contactless smart cards can be used for identification, authentication, and data storage. They also provide a means of effecting business transactions in a flexible, secure, standard way with minimal human intervention.
