There are several things in place to ensure you are picking up the correct fare / rider (s). They may or may not all be in place, but 9 times out of 10, the one main thing that is - is their name. Exceptions being for example if a member uses the app to get another passenger home, who doesn't have the app. And if they have entered a destination in with their request, and in your app, if it's not showing or it's incorrect, this should also be a CLUE YOU HAVE THE WRONG FARE. Good Gawd, it's not rocket science.
