Hello,

The SCARD_ATTR_* "commands" are driver specific.

In your case I suppose SCARD_ATTR_VENDOR_IFD_SERIAL_NO is not
supported by your smart card driver. I think it should return the
serial number of the IFD (the driver) and not the serial number of the
card.

Contact your driver author to have a list of supported SCARD_ATTR_*
commands. For example, for my CCID driver [1] the list of supported
attributes is available at [1].


Thank you, I will contact the author.

And now I realise which question I should have asked in the first place. How do I read the serial number from the card using JPCSC, if there is such a thing on the card? Is it even a standard feature to do so?
