The history of our monetary system is a long and exciting tale; barter turning to the use of gold in some places, wampum (shell beads) in others. Sixty years ago the first credit card, Diners Club, came into existence. Today almost all North Americans are packing plastic, if not credit then certainly debit. Within the past fifteen years we’ve seen the rise of e-commerce with companies like PayPal, creating economies within economies. So what’s next on our path of monetary madness? Well if you’ve recently been to Japan, or are dating a Japanese lady (recommended) you probably already know the answer: wireless payment via your cell phones.
