Major Security Contract Clinched: Infineon to Supply Next Generation of Security Controllers for German ID Cards, Europe’s Biggest ID Project

Neubiberg, Germany – December 7, 2010 – Semiconductor manufacturer Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) is supplying its next generation of security controllers of the SLE 78 product family for the new German ID card. The German authorities have been issuing the new electronic ID in chip card format since November 1, 2010. Infineon is providing a significant share of the chips for Europe’s biggest ID project. Currently, around 60 million German ID cards are in circulation, usually valid for ten years. About 6.5 million ID cards are issued each year. Infineon’s ”Integrity Guard” security technology is used in the new ID card. The product family SLE 78 is based on this revolutionary technology, specially developed for applications in which stored data needs an especially high level of protection. Such applications include government ID and payment cards. “Right from the start, Infineon has played a significant role as an innovation driver in shaping the over 25-year history of the chip card. We are delighted that our new generation of security controllers are used in the German ID card. It confirms our technological expertise in government identity documents”, said Dr. Helmut Gassel, President of the Chip Card & Security Division at Infineon Technologies. Electronic ID documents gaining ground in Europe The use of contactless technology in electronic passports has stood the test of time. Now it is the turn of the ID card. Many EU member states have started its introduction, and about 80 percent of electronic ID cards in Europe today contain Infineon security controllers. By the end of 2011, 14 of the 27 EU member states will have started issuing the electronic ID card to their citizens. As a result, almost half of the 500 million EU citizens will have obtained such an ID card within the next years. The SLE 78 chip in the new German ID card has been certified by the Germany Federal Office for Information Security (BSI). Infineon developed the chips for the ID card in Neubiberg near Munich (Germany). The chips are made in Dresden (Germany) and the chip package comes from Regensburg (Germany). The SLE 78 family based on “Integrity Guard” security technology is Infineon’s latest generation of security chips. Infineon is a long-standing global market leader For more than 13 years in succession, Infineon has led the global market on chip card ICs.
