CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). For brevity, this Standard will be referred to as \"CAN/CSA-ISO/IEC 17839-2\" throughout. At the time of publication, ISO/IEC 17839-2:2015 is available from ISO and IEC in English only. CSA Group will publish the French version when it becomes available from ISO and IEC. Scope This part of ISO/IEC 17839 defines the following: dimensions of a Biometric System-on-Card type S1 and type S2; position and size of the biometric capture device; minimum requirements to a Biometric System-on-Card with respect to mechanical durability, and man-machine interface and ergonomics. The standardization of other on-card devices such as an electronic display or a keypad is outside the scope of this part of ISO/IEC 17839.
