Breeze cards (http://www.breezecard.com/) are stored value smart cards that passengers use as part of an automated fare collection system which the Metropolitan Atlanta Rapid Transit Authority (MARTA, http://www.itsmarta.com/) introduced to the general public in October 2006.
Breeze cards are supplied by Cubic Transportation Systems (http://cts.cubic.com/), an American company that provides automated fare collection equipment and services to the mass transit industry.

The Breeze Card uses the MIFARE smart-card system from Dutch company NXP Semiconductors, a spin-off from Philips. The disposable, single-use, cards are using on the MIFARE Ultralight while the multiple-use plastic cards are the MIFARE Classic cards.
There have been many concerns about the security of the system, mainly caused by the poor encryption method used for the cards. See Security of MIFARE Classic (http://en.wikipedia.org/wiki/MIFARE#Security_of_MIFARE_Classic) for details.
