If you are planning on using your credit or debit card when you go on holiday abroad then you might want to check how much your bank charges. That's the message from some financial experts who warn that many holidaymaker's are charged much more than they expect for using their card abroad. Many banks have increased their fees for using cards abroad in the past year. These increases mean that if you withdraw £100 from a cash machine abroad you could be charged as much as £4.95 whereas spending £100 on a credit card will incur a charge of up to £3. Whilst the charges may seem relativity small if you unaware of them it can soon add up so the message is to check how much your bank charges before you go away.
