Credit/Debit Card Fraud – How To Prevent It?

Really I am seeking some suggestions on this one. What do you do to limit fraudulent attempts to use your credit or debit cards? I have had to cancel two credit cards and one debit card due to attempted fraud since January. Thankfully both companies blocked the attempts.

I think the most recent may have come through a PayPal phishing attempt saying my account was limited and I needed to update it. Yet one fraud department told me PayPal was the safest way to charge online. Another told me that Amazon is not a secure site.

Please just send me your suggestions.

Thank you.
