The service is available and works the same as with traditional paper and electronic tickets (BIT100, Roma24H, monthly pass). The two "taps" to change between metro line C and metro line A or between Urban Railways and Metro lines A or B, if made within the validity period of the ticket, are considered as one single tap and there will be no further charge, exactly as it happens at the exit turnstiles of metro line B1.
