Not for now. To pay with tap & go ®, the journey must necessarily begin either at metro stations or regional railway stations (Roma-Lido, Termini-Centocelle, Roma-Viterbo urban section) equipped with turnstiles. From there you can continue your journey on surface vehicles, within the 100 minutes of validity of the ticket. If you want to continue your journey on Cotral vehicles, you must have downloaded the Atac tap & go ® application (only on Android devices with NFC technology), necessary in case of on-board controls. At the moment you cannot use tap & go ® on Trenitalia trains.
If you use your card as a monthly subscription (whitelist) you can travel on the entire Atac network during the charged month.
