Discover claims some kind of alliance with UnionPay, RuPay, and Troy.
I’m still trying to figure out the whole situation. It seems like “Discover” is more of an alliance system, rather than a “one person controls the whole network” deal (like Visa or Mastercard). It means that they cannot give as strong guarantees, but members of the alliance seem to be largely compatible.
