The kiosk doesn't forget points or who you are. As long as the Contact exists within your Contact Database in your account they are able to check in on the Kiosks.
Because there are so many businesses that have multiple locations or want to share their points with other local franchises, the iPad won’t store information on the device itself.
It requires an internet connection to be able to look up how many points you have or who a contact is.
