I found a bit of specific info on the Cards.
[2] a Kimoyo card. Kimoyo is Bantu for "Of the Spirit." It is kind of a Mother Box with tons of applications. It is basically a Palm Pilot amped to the Nth degree. It functions a lot like the Avengers' communicards, but with a lot more practical applications (in issue #14, for example, Panther called up a virtual schematic of a jumbo jet's cockpit controls and took command of the plane, landing it safely in a river).
So it's just useful not some reality warping supercomputer.
