Electronic punching (e-punching or EP) is a faster, better way to record your visit
to each control on an orienteering course. Instead of carrying a paper card and punching
it at each location, you wear a plastic e-stick, or "finger stick", which contains a microchip.
At each control site, you insert the finger stick into a control unit, which records the control
number and time onto the microchip.
When you finish the course, you download the data at a transfer station, and receive an
instant printout of your time and splits. Even better, you can view compiled printouts
that show everyone's splits for the course.
