Government and military employees and contractors who need to access secure U.S. Department of Defense (DoD) or civilian federal websites on a Mac - which usually requires a login with a Common Access Card (CAC) -- now have a simpler method of doing so. Thursby Software Systems has released PKard for Mac software. PKard is short for Public Key Card and pronounced P-card, and the software works with all current types of CACs and the hardware readers, including the next-generation "Oberthur" and "Gemalto" type cards.
