A little switch on the card might be useful though. Especially if it can be set/unset by the base station (might be getting mechanically complicated).

For example, perhaps a game that has a general flow of: players have their cards, there’s a central base station, but most play is not digital. Maybe they somehow battle their cards, they can go around and battle people as much as they want, but their “moves” are tied to the switches and when they use a move, they flick the switch off (wonder if it could be made to actually get stuck in position, to provide physical feedback indicating that the moves are “used up.”)

Then, when they want, they go back to the Pokécenter — I mean, oops, base station. It recharges their abilities (unflips the switches), maybe runs some “level up” logic, etc etc.

I mean, this quickly started to stretch credibility as far as the mechanism goes, but the idea of giving the players/game designers a couple bits of state that they can toggle away from the base station might allow more asynchronous type games.
