I currently have a PC/SC compliant smart card reader (ISO 7816). I need two seprate windows applications that do two things:
* A program that allows me to specify a value to write to the card. The value would be MD5 hashed and written to the card
* A program that triggers a screen saver and waits for a card to be inserted into a reader. When a card is inserted, the hash would be read from the card and transmitted via a TCP Socket. The computer would listen for an "OK" signal, and then disable the screensaver untill the server sent an "END" at which the screensaver would be reactivated.
