How about answering my question about hardware signals from the card reader?

If you cannot use the hardware to detect whether the device is present, you have to start communicating with the device.
Even if this is the unfortunate case, the device should respond fairly rapidly without worrying about degrading performance from a user perspective.

Perhaps this article[^] can give you some ideas.
