Most fares will increase by €0.10. fares will not. For regular travellers not already on a taxsaver card for example perhaps it makes sense to consider switching to a Smartcard (even allowing for the initial €3 non refundable charge)? I think a single zone adult journey is still €1.25 on the Smartcard and it's €1.40 (off peak) or €1.50 (peak) from the ticket machine and presumably the latter are increasing to €1.50 and €1.60 respectively with the Smartcard fare remaining the same.
