Imagine walking into Jamba Juice for your favorite smoothie fix, and when it's time to pay, instead of pulling out cash or a credit card, you just tap your phone on a reader, and you're ready to go.

For more than a decade, Republican presidential candidate Ron Paul has had to deal with questions about why a newsletter he published in the 1980s and '90s included some racist writings.
