Abstract
A data transfer device, having first data interface means for exchanging data with a data processing system, second data interface means for exchanging data with a user of the data transfer device, and control means for controlling data transfer between the first and second data interface means. The control means are configured for receiving control data from the first data interface means for selectively enabling data exchange between the first and second data interface means. The control means can be configured for enabling part of the first and second data interface means for operation in a first or open mode, and for enabling the second data interface means for operation in a second or secure mode of operation. The second data interface means may comprise Input/Output means for secure data exchange with the first data interface means under the control of program execution data operative in the data transfer device and comprised by the control data.
