TIB-branded buses are all tap in/tap out contactless bank card, though the buses of EMT Palma (who run the A1 bus from Palma Airport to Palma, in particular) are
cash only on board. There are however a few TVMs scattered around (at least one at the Airport and one upstairs outside the Estacio Intermodal).
Rail timetable here:
One main railway line (Palma to Inca) which then splits into two, with one train per hour to Manacor, and another to Sa Pobla. On weekdays for most of the day you'll find a fairly frequent service on the Palma to Inca section - it's much reduced on weekends (just 1tph to each of Manacor/Sa Pobla, nothing additional terminating at Inca). Scenery-wise, it's quite pleasant once you're past Inca.
There's one Metro line to ParcBit - it's not all that thrilling but again, fairly frequent on weekdays. It's more limited on Saturdays with nothing at all on Sundays.
Metro/train is again tap in/tap out contactless, so easy enough to do. You could very easily complete the network in a day with time to wander around if you wished.
All trains/Metro services (and long distance bus services branded with the TIB logo) leave from Estacio Intermodal in Palma.
