Hear me out: With the Cap1/Discover merger, why not make a dual-network card that falls back to Visa/MC?

Hey everyone,

So with the whole Capital One acquiring Discover thing, we know they're planning to transition a bunch of their existing Visa and Mastercards over to the Discover network. As someone who travels, my immediate thought was how much this is going to suck for international acceptance. Discover is fine in the US, but take it abroad and it’s a total coin toss.

But it got me thinking—why doesn't Capital One just issue a multi-branded card?

Some international cards (like a lot of Chinese UnionPay cards) do exactly this. They run on their home network first, but if the merchant's terminal doesn't support it, the transaction just falls back to Visa or Mastercard.

Imagine a Capital One card that defaults to the Discover network so Cap1 saves on those sweet, sweet swipe fees (which is the whole point of this merger anyway). But, if you're at a cafe in Europe or Asia that only takes Visa/MC, the payment still seamlessly goes through on the backup network.

It feels like the best of both worlds. Cap1 keeps their transaction fees in-house 90% of the time, and we don't have to stress about carrying a backup card just to buy a coffee overseas.

Is there a regulatory reason they can't do this in the US? Or is it just a massive technical headache? Would love to hear your thoughts on this. Maybe if we talk about it enough, the Cap1 product managers lurking in here will take notes lol.
