What is the “Contactless ticket” extension for?

"Contactless ticket" is an extension to the CTS mobile app. It allows you to create a secure, dematerialised transport card on your smartphone to store all tickets purchased via the CTS mobile app.

Once the extension is installed, you can buy tickets whenever and wherever you like. Your smartphone becomes your travel card, and you can validate your tickets simply by placing your phone on the contactless validators, just like with your Badgéo card.
