Data transfer device, transaction system and method for exchanging control and I/O data with a data processing system
First Claim
1. A data transfer device, having a first data interface for exchanging data with a data processing system, a second data interface for exchanging data with a user device, and a control unit for selectively enabling data transfer between said first and second data interfaces in one of an open mode and a secure mode of operation, wherein said control unit is configured for receiving control data associated with an application to be processed by said data processing system and for providing an authentication check on said control data for setting said data transfer device in either one of the open and the secure modes of operation.

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.

29. A method of exchanging data with a data processing system using a data transfer device having a first data interface for exchanging data with said data processing system, a second data interface for exchanging data with a user device, and a control unit for controlling data transfer between said first and second data interfaces in one of an open mode and a secure mode of operation, said method comprising:
-
transferring control data from said data processing system to said data transfer device, the control data being associated with an application to be processed by the data processing system; and
performing an authentication check on the control data to set the data transfer device in either one of the open and the secure modes of operation. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)
