A friend of mine is going to UK shortly. I gave this friend a few pointers about credit cards and bank accounts. I want to share one of them with you also.
When you are going abroad on vacation, please inform your credit card companies and bank that you will be on vacation in “these” foreign countries from this date to this date. They will put a note on your account to this effect.
As we all know, the credit card companies and banks are very watchful to avoid any fraudulent charges to our accounts. When they see someone charging your account in a foreign country, they immediately suspect fraud and, most of the time, block your credit card or bank account. If you are in a foreign country and enjoying your vacation, and if your credit card and/or bank account is blocked, it will put you into a lot of hardship.
However, if you inform them prior to your departure, they will know that the charges from these places are legit.
This happened to me personally. I was in a small town in Tamil Nadu. Bought some silk sarees for my wife, and some gold and silver thru my credit card. Also withdrew some cash thru ATM using my American bank debit card. The next day I came to know that my credit card and bank debit card were blocked. I called them from India and they told me about their suspicion. I explained and they informed me that I should let them know prior to my travel to a foreign country. Lesson learned.
