I read RS travel book that Rick Steves himself advises the travellers not to use debit card for purchases because the potential charges incurred by a thief will stay on your account while the bank investigates. I'm not sure what charges mean exactly? Does he refer to 2.8% international processing fees? Steve advises the travellers to use credit cards. What are your thoughts?
"International processing fees, also known as foreign transaction fees, are charges added to your credit card or debit card transactions when you make purchases or withdrawals outside of your home country, or when the transaction is processed by a foreign bank. These fees are typically a percentage of the transaction amount, usually ranging from 1% to 3%."
For example, I paid for the hotel reservation in GBP117 through debit card after from the booking.com shows local home currency$156 that i clearly see. After the purchases, I checked the bank app and am surprised to see the bill being reflected as local home currency$179, not $156. I find it a bit steep - $156 and $179. It made me wonder if Steve refers to this?
