8Relying Only on Cards Without a Backup Plan

While credit and debit cards are widely accepted in Europe, there are still plenty of places, especially in small towns or markets, that only accept cash. Tourists who don’t carry local currency may find themselves stranded.
How to avoid it: Always have some cash on hand, particularly in rural areas or for small purchases. Use ATMs to withdraw money in local currency, and inform your bank of your travel plans to avoid card blocks.
