摘要： An arrangement for effecting secure transactions having a device interfaced to at least one communications network is proposed. The device has two modes of operation, and includes a controller that controls the device in a first mode of operation and a display coupled to the controller in the first mode. The device further includes a secure part for controlling the device in a secure mode of operation. This secure part has a secure memory for storing data. This memory is directly coupled to the display in the secure mode of operation. Preferably, the device also includes a keypad or other input device that is directly coupled to the secure memory in the second mode. The hardwired connections to secure memory in the secure mode ensures that data shown on the display is indeed the data that is processed and signed off in the secure mode of operation.
