Debit cards are quite secure, at least here, but we're many years ahead of the US when it comes to credit/debit cards.

The magnetic strip is never used(haven't been used the last 10 years, at least), a PIN is always required at PoS and for many issuers an electronic multistep authentication process is required to order anything online with the card.

And if something still where to go wrong then you'll get your money back.
