I am working on an registration application which would be used in a live "museum" type experience. Essentially to enter the museum you need to register for a personal account to receive a ticket.
I am considering tapping Facebook/Twitter/Google APIs in order to decrease the total registration time per user by pulling their information through the respective API. I can find information relating to using the APIs for website registration however my question is related to abandon rates when offering this on a public terminal.
Does anyone have non-anecdotal evidence which supports or denies increased abandonment rate on public (non-personal) devices when requiring Facebook, etc account information?
