A researcher at the University of Cambridge has developed a new device that can act as a trusted intermediary to ensure the validity of electronic transactions. The device, called the Smart Card Detective, is a small, card-sized piece of equipment that, among other things, can be used to verify that the amount shown on a terminal screen is actually the amount of money that is debited from a user s account. Device’s creator, Omar Choudary, said he has built two prototypes of the SCD.
