As part of going “full mondo”, I have my mondo card linked to my Amazon account. Amazon are a bit funny in that they take the payment when they ship the product, rather than when you buy it - So it basically happens at an unknown time, meaning if I don’t have enough money it gets declined.
With a regular bank, I would usually go into overdraft at this point. I can see here that this has been talked about a bit before, and I guess it’s not something Mondo want to consider (at least for now).
So here’s a different solution: When a user buys something from somewhere like Amazon, they can input that “planned” payment into Mondo, and then when the real payment comes through, “reconcile” it. That planned payment would count against your balance, making that amount essentially “locked”, guaranteeing it will get paid.
I can imagine this being really useful as well later for bills, rent, etc.
