With the wide use of credit cards at stores or restaurants, and with online shopping becoming more and more popular, credit card fraud has been on the rise. Pay attention to the following points and try to avoid credit card fraud.(14)First, as soon as you receive your credit card, sign the back of it. If you lose a card that doesn’t have your signature, someone else may sign it and use that card as you. There should be instructions on the credit card regarding activation. You may need to call their phone number from your home phone for your added security.(15)If you receive an email asking for your credit card details, delete it. Never respond to such emails, even if they seem to be official emails from your bank.(16)You have to choose a PIN for cash advances with your credit card. Never write that PIN on the credit card, in your wallet, or keep it with your credit card. If your credit card is lost and someone else finds it with your PIN, they can withdraw cash using your credit card. For shopping online, don’t enter your credit card number into an unsecured website.(17)Before entering your credit card online, make sure that your browser displays the secure lock, usually in the bottom right corner, or towards the top in some browsers. The website should also display a certification from trusted companies.
