摘要
The method involves modifying a control program in a smart card reader terminal i.e. payment terminal, such that the program calls a secret command that is pre-inserted into an authentic smart card and is different from a set of standard and public commands such as payment commands. Authenticity of a smart card i.e. payment card, is detected if the secret command is recognized and/or processed correctly, or presence of a clone smart card e.g. clone payment card, is detected if the secret command is not recognized and/or is processed wrongly. Independent claims are also included for the following: (1) a smart card reader terminal comprising a control program receiving and executing unit (2) a computer program product comprising instructions to perform a method of detecting a smart card (3) a computer program product comprising instructions to perform reading and/or writing in a memory and mathematical and logical operations.
