Markus, a German businessman, prepares his trip to Paris

Using the ratp.fr website, Markus purchases his Paris Visite travel pass online, which allows him to take Orlybus from the airport into town as soon as he arrives. To find his way around the network, he uses the Next Stop Paris app. Especially designed for visitors, the app can be used offline and has been translated into 10 languages. www.ratp.fr/touristes/
