In the light of increasing international trade and intensified human mobility the knowledge of dynamical and statistical properties of human travel is of fundamental importance. I will report on our recent discovery of universal scaling laws the geographic dispersal of bank notes and their implications on global human mobility patterns. Based on the idea that the geographic circulation of money is an excellent proxy for human travel, we analyzed the movement patterns of over half a million individual dollar bills registered at the popular online bill-tracking website www.wheresgeorge.com. I will report that in the global dispersal of money long waiting times compete with long jumps in space and that this can be accounted within the continuous time random walk model yielding bifractional diffusion equations on large scales.
