Abstract: A personal device is to be connected to a terminal and being equipped with a computerized method for establishing a trustworthy connection between a user via said device and the terminal which is connected to and authenticatable by at least one server which is authenticatable by the device. In the case the device is coupled to the terminal, a first authentication step is initiatable during which the terminal authenticates itself to the server, upon success of which, between the server and the terminal, a first authenticated trusted connection is established. Subsequently a second authentication step is initiatable during which via the established first authenticated trusted connection the server authenticates itself to the device, upon success of which, between the server and the device, a second authenticated trusted connection is established. Subsequently at the device during a first messaging step, from the server via the established second authenticated trusted connection, a terminal authenticity message is receivable confirming the established authenticity of the terminal. Subsequently during a second messaging step an authenticity output message is communicatable from the device to the user via a device output of the device and/or via a terminal output of the terminal.
