Well in the Uber example you're allowing payments to Uber, not denying them.
But you do have a very good point about denying pay-after-use type transactions, I'm not really sure what they're doing about that.
- pavel_lishin 9y agoWasn't their example all about limiting the number of rides you can take? So at that point, you'd eventually be denying them, as I understand it.
- Sean1708 9y ago> Uber card: Let’s say you give your daughter R500 pocket money each month, but you’re worried she might run out of money and be unable to afford an Uber home. So you write a little code and give her a Root card that a) gives her a limit of R500 per month, and b) lets her take as many Uber rides as she needs (enabling her to spend beyond the R500, but only for Uber) That's the one I was thinking of, note the "lets her take as many Uber rides as she needs".
- pavel_lishin 9y agoOh, I missed that example! That is actually pretty cool.
- Sean1708 9y agoYeah there's a "Press Kit" link in the footer which should definitely be more obvious because it gives a lot more info than the front page.
- netsharc 9y agoThen the daughter trades Uber rides for cash.. (you can order an Uber to give a friend a ride without you needing to be in the car yourself). I kid, the possibility of putting spending rules as code is neat.
