Where can I find a mac utility or terminal script to read the contents of a smart card?

Recently I found a USB smartcard reader and have been trying to find a way to read the data off an old card I found. It’s not for a shady purpose or anything just curiosity, which I’ve been unable to satiate because of a lack of mac tools. I already have found the apple article on how to use it to log in, but that still doesn’t help me change the pin or access the ROM etc. Is there something I’m missing or perhaps a terminal command that I can access it through?
