Chip + pin debit cards are reasonably safe. Credit cards are much less safe, essentially every time you enter your details there is one more party in on the secret.

I try to use my CC online as little as possible and in the real world only when I have the card in view at all times and the pin verification terminal is under my control while I enter the pin, and crucially, contains the card (so I won't use it if the terminal is in one spot and the card in another).

I never use swipe.
