The thing that scares me about this idea is the effect it would have on the donor if they didn't see their donation reflected immediately in the feed. Not only is it less exciting, but it potentially opens up questions about where the money is in the meantime.

I will strenuously avoid this turning into anything resembling a bank - it needs to be more like a "take a penny, leave a penny" tray sitting on a Starbucks counter. If someone want to be a jerk and empty the tray into his pocket, so be it. They're just a jerk who I'm sure will get what they deserve in life.

Fingers crossed, j

If you go with the deposit only card option, you could adjust your feed to display the aggregate of the two cards; but you're effectively capping an individual transaction to $20. The donor therefore sees their changes reflected in real time, but any cheats are limited (hopefully a cashier would get suspicious / frustrated if someone tried to work around the $20 limit by going multiple times in succession).
