Create a cash dispensing server at Apple’s datacenter, to which iPhones, iPads and Macs can connect via a specialized app. Need some quick cash right now and there’s no ATM around? Launch the Cash app, and tell it how much do you need. The app picks up your location, and sends the request for cash to nearby iPhone users. When someone agrees to front you $20, his location is shown to you on the map. You go to that person, pick up the bill and confirm the transaction on your iPhone. $20 plus a small service fee is deducted from your iTunes account and deposited to the guy who gave you the cash.
