The service is available and works the same as with traditional paper and electronic tickets (BIT100, Roma24H, monthly pass).

The "taps" to change between bus-metro/railways, metro/railways-bus and bus/bus, if made within the validity period of the ticket, are considered as one single tap and there will be no further charge.

To avoid potential penalty fares, remember to "tap" your card each time you change means of transport. Taps made within the validity period of the ticket do not count as a new payment. Therefore, if you are travelling on surface vehicles, always remember to "tap" before the 100 minutes run out.
