How can I protect personal information while traveling abroad?

Do not use public computers or public wi-fi connection for online financial transactions. Also, do not give out much personal details in the social media and give passwords that are difficult to guess.

There are 101 ways to protect yourself from identity theft. For instance, use 2-step authentication whenever and wherever possible.

Lock your smartphone and use cash whenever possible.

If possible, "Unpack" critical documents before you leave home. Your social security card, bank statements, medical documents, checkbook. etc might get mishandled by the crooks if any how they get their hands on your baggages.

As "SC" said earlier, use cash instead of credit cards, and use only bank ATM's .

Never log in to your account using any unknown person's phone or computer. Don't give your debit card to the waiter for paying the bill. Keep enough cash as well.
