Technology
Tcard was based on smart card technology and employed the 13.56 MHz MIFARE technology. A MIFARE DESfire chip embedded in the Tcard communicated with the card reader through radio-frequency induction technology. These types of cards require only close proximity to an antenna to complete the transaction. They are often used when transactions must be processed quickly or hands-free, such as on mass transit systems, where smart cards do not have to be removed from a wallet for use.
Like smart cards with contacts, contactless cards do not have a battery. Instead, they use a built-in inductor to capture some of the incident radio-frequency interrogation signal, rectify it, and use it to power the card's electronics.
Similar systems operate in many cities in Asia, Europe, and North America. Particularly successful examples including the Octopus card of Hong Kong (also developed by ERG) and the Oyster card of London. The SmartRider system was launched in Perth in 2007, the TransLink Go card was launched in Brisbane in 2008, and myki was launched on a limited basis in Geelong in late 2008, as the start of its eventual introduction in Melbourne and rest of the state of Victoria.

Famous quotes containing the word technology:
“The real accomplishment of modern science and technology consists in taking ordinary men, informing them narrowly and deeply and then, through appropriate organization, arranging to have their knowledge combined with that of other specialized but equally ordinary men. This dispenses with the need for genius. The resulting performance, though less inspiring, is far more predictable.”
—John Kenneth Galbraith (b. 1908)
“Technology is not an image of the world but a way of operating on reality. The nihilism of technology lies not only in the fact that it is the most perfect expression of the will to power ... but also in the fact that it lacks meaning.”
—Octavio Paz (b. 1914)
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
