developing simple apdu sender using winscard

In Windows operating system, we need WinSCard library to send and receive APDU. APDU is Application Protocol Data Unit, which is used to communicate to a smart card. There are two categories of APDUs: command APDUs and response APDUs. Using command APDUs, we can send an instruction to the smart card then it will yield response APDUs. In this article, we are going to develop a simple APDU sender that can be used to send the command APDUs to a smart card then expect the response from it. The complete source code can be found on this GitHub repository link Continue reading
