I realize this is a dynamic situation, so there may be no absolute answer. I’ve read conflicting information online, as well as in recent guidebooks on the necessary use of cash in smaller villages in Portugal. I realize tipping anywhere, even in the US, is best done in cash. Smaller, family run businesses can reduce overhead by only accepting or preferring cash payment. Vendors of inexpensive items would probably prefer or require cash. I’m curious what recent experiences in smaller villages have been with regards to cash. A requirement or culturally appropriate…or even a nonissue? Thanks for you input.
Draw out some euros from an Atm (preferably a bank)
Use as needed.
ATMs are everywhere. So are credit cards. Yes some vendor may be off the grid. Pay cash. No problem and little expense.
What is not everywhere is the compulsion to tip. Outside of North America, any sort of service charge will be made plain. Keep your cash for exceptional service. European credit cards do not provide a tip service.
I am told that the best ATMs to use in Portugal are Multibanco. I rarely bring more than 100 euros to Europe, and that is always left over from a previous trip. I don't purchase euros prior to travel.
I was in Portugal last year. I was able to use a card most places, but I did run into a few places that only took cash. This also happened in one of the small restaurants where I ate lunch in Lisbon so it is not exclusive to villages. I’d suggest just having some Euros on hand. As others have mentioned, make sure to use a Multibanco (look for ”MB”) to avoid fees.
Just returned from 18 days in Portugal in March. It is in transition with cash vs credit cards (unlike Italy and Greece last year that had gone credit card even for small items).
Most places took cash especially museums, but did find some cases of cash only in tourist spots - Pinhao in Duoro was very cash based restaurant and hotel, and so was Lisbon's Bairro Alto area was cash only restaurants.
