People walking around with their wallets sticking up out of their back pockets is a sight pickpockets in Japan are only too used to being grateful for.
Carrying a credit card is like having a wallet bulging with cash, typically 100,000 yen or more at a minimum, just waiting for you to spend whenever you want to. But just as you shouldn't leave your wallet out of sight and out of mind in your back pocket, so you need to take a few precautions with your card.
Credit card expert Daniel J. Lintz, the director of corporate communications Japan for Visa International Asia Pacific Ltd, told The Japan Times in a recent interview that most credit card fraud takes place when you take your eyes off of your card.
