CEN/TC 224/WG 3 - Device interface characteristics

This European Prestandard specifies mandatory and otional interfaces between devices and machine readable cards, as well as other interfaces only to the extent that they are related to the processing of the machine readable card. It specifies the characteristics of each particular interface, and provides the means, through the use of bitmap coding, of readily identifying the capabilitiesof devices in order to ensure the compatibility between specific devices and cards. As far as technical specifications are concerned, it refers to other existing standards.
