I'm working on a project related to smartcard security, and I wanted to conduct some tests. But I cannot acquire a card reader to test with at the moment. Is there a way to use Javacard toolkits without having a physical card and card reader? (e.g. an online library that can completely emulate a card without using a physical card reader)
The JavaCard SDK distributed by Oracle includes an emulated card that can be launched as an Eclipse plug-in. https://www.oracle.com/java/technologies/javacard-sdk-downloads.html
I haven't used it for a long time now, but it was extremely useful for debugging some applications.
