You can install the free Wēpa app on a smartphone from the App Store or Google Play, or download the app from this link.
Having the Wepa app also creates a quick and easy way to log into a kiosk. Once you have downloaded the app and logged onto your account on your smartphone, you'll find a small Wepa icon in the bottom right corner that reads "Tap to Login". Once you have clicked into that icon, hold your phone up to the app reader to the left of the kiosk screen.
