Hi Nancy,
Uber is indeed present in Ireland, but it might be good to know Irish law requires that anyone carry passengers for money must have a taxi license, so there is not that much difference between a regular taxi and an Uber one.
Both Uber taxis and regular taxis accept payments by credit card. It's always a good idea still to ask the taxi company or driver if they accept card payments before taking the taxi. In case they don't, you'll find that they will be more than happy to stop off at an ATM so that you can withdraw
money. There are plenty of ATMs available all over the island.
Tipping your driver is never expected, but always appreciated. :)
I hope this helps! And it's so nice to see you're getting excited about your upcoming Ireland trip! Will you be using
taxis and public transport to explore the island or will you be going on tours as well?
Warm regards,
Joris
