Social scientist Heather Schlegel is a futurologist. She recently funded (via Kickstarter) a TV series called "The Future of Money" which envisions future methods of payment that seem sci-fi.

Heather's view is that If the last three decades revolutionized the information and telecommunications industries, the next three may upend the basic tenets of finance: currency, credit and banks, as well as payment and transmission systems. Your children may even ask you, “What was it like to see that old-fashioned building called a bank?”
