Could Cardano Work/ be introduced in a points redeemed or rebate program?

I was suggested a video on youtube “How airlines quietly became banks”. It immediately made me want to ask the question here: Could Cardano work/ be introduced in a points redeemed/ rebate program. Perhaps the answer is obvious. Yes and No is where I’m at right now.

I think so. It would be easier with a custodial wallet since many people don’t know what to do and if they do they may not know what wallet to use. Too bad there’s no standard such that you could receive any cryptocurrency. I think people would love if cryptocurrency wallets were more like real wallets which accepts dollars, euros, swiss francs equally well.
