France: 1999 Cyber-Comm specification for trusted smart card readers for consumer usage Banks, Credit Card and Smart Card Companies Authentication of smart card and keypad input

performed in reader Secure output – LCD display on reader

EU: July, 2001 FinRead specification for trusted reader devices Banks, Governments, Technology Companies Programmable, multi-application/services platform

through Java applets Global Trust Authority as source of trust for system Integrated services business model for deployment
