The TDK EMV-Ready firmware application has been designed to allow immediate and seamless integration of a card reader function into any microcontroller-based system. The application software includes a Command Interpreter layer, operating on a challenge/response scheme, dedicated to smart card management. The format of these commands is based on the PC/SC specification, suitable to either embedded or PC applications. The EMV-Ready firmware also includes a proprietary communication protocol that guarantees the integrity of the data exchanged between the host and the TDK controller. Error detection and correction are supported by this protocol. Integrating a smart card reader function into a system can be a time-consuming task, requiring in-depth smart card experience especially when it comes to implementing the software protocol layer used to communicate with the smart cards. It can get even tougher when the card reader must go through a formal EMV (Europay, MasterCard, Visa) type-approval process. With TDK Semiconductors 73S11xxF circuits, pre-programmed with the EMV-Ready application, the implementation of such a card reader function can be done immediately by connecting the 73S11xxF circuit to the systems host through a serial interface. The application includes the EMV test routine that allows the immediate evaluation and further submission to accredited laboratories. In addition, connecting extra peripherals, or using other built-in features is facilitated by the easy addition of custom commands, making the whole solution extremely flexible. Availability TDK EMV-Ready executable software stack is available free of charge, royalty-free with TDK Semiconductors 73S1112F and 73S1121F circuits and demo boards.
