The chip's core characteristics - fast, innovative, reliable and secure, as described by the 'fire' part of its name - are supported by a unique combination of flexible memory organisation structure alongside impressive data transaction rates making it ideal for secure contactless ticketing services.
"Service providers, system integrators and smart card manufacturers who have traditionally relied upon contact smart card technologies have begun to adopt contactless technologies that offer enhanced consumer friendly system designs alongside comparable security levels", said Reinhard Kalla, Business Line Manager for Chip Cards, at Philips Semiconductors.
"Philips' Mifare portfolio is the largest contactless infrastructure base in the world.
The addition of Mifare DESFire to the portfolio provides the industry with a highly secure, high speed, cost effective silicon solution and is solid evidence of Philips' continued innovation in the contactless identification market".
Mifare DESFire operates at a distance of 10cm and in accordance with the international standard ISO14443A perfectly meets mid-end transportation segment needs including security and cost effectiveness.

System solution combines everything an OEM needs to implement TV functionality in tomorrow's cutting-edge mobile systems, including hardware, complete DVB-H and DVB-T software stacks and security
It features a 4Kbyte nonvolatile memory, a high speed triple-DES data encryption coprocessor, a flexible memory organisation structure, a mutual three-pass authentication technique together with a true random number generator and an anti-tear mechanism to guarantee data integrity during contactless transactions.
Philips' Mifare architecture platform is the industry standard for contactless transport ticketing solutions.
The platform is based on advanced technology that can be evolved to meet the needs of changing market conditions.
At present there are 250 million Mifare cards in circulation and 1.5million installed reader/writers worldwide.
The scope of Philips' Mifare architecture platform enables service providers to conveniently expand their networks to include a wider range of services while reducing installation and maintenance costs.
High volume manufacturing processes and partnerships are in place that will ensure that Mifare DESFire is rapidly used in contactless systems worldwide.
Other established Mifare smart card IC solutions like Mifare UltraLight and Mifare Prox offer low- and high-end solutions, respectively.
A demonstration of Mifare DESFire will be on show at Philips' CarteS 2002 booth (3H 031) highlighting the industry's next step for contactless chip card technology.
The CarteS 2002 exhibition and conference runs until Thursday 8th November at the Paris-Nord Villepinte Exhibition Centre in Paris, France.
First customer samples of Mifare DESFire will be available in Q4 2002 and production ramp up is scheduled for Q1 2003.
