So, imagine a situation - you want to eat, and the nearest cafe, where you threw a table his mortal body, does not accept the card. ATM nearby can not see - what to do? Apple engineers offer out under difficult name «ad-hoc cash-dispensing network» (self-organizing network of cash). All you need is to run a custom application, and enter the desired amount of cash. On the next point, the application distributes the request to other users in the vicinity (using location information of the first user).
When someone close to you from the user agrees to give you cash out of your wallet, you tell him your exact location to meet and get your bill. It is also proposed to use the card, where your future lenders will be displayed as asterisks (if the request for extradition made of money), or in the form of question marks (if you have not received a request), or a cross (if refused to comply with your request.)
