<p>The method involves allocating two zones of a screen of a payment terminal to two sets of information using filters and a direct memory access (30), independently from an open operating system e.g. UNIX(RTM: powerful multitasking operating system), where one set of information is edited by a secured operating system. The two sets of information are transferred to the screen under an exclusive control of the secured operating system to produce a security visualization of the set of information. The two sets of information are combined using a real video RAM (34). An independent claim is also included for a device for securely visualizing information on a screen of a payment terminal.</p> |
