Okay, well you do more than most folks.
Keep in mind that Target’s recent fiasco was not a result of online security failures but physical security faults at point-of-sale systems. The people who were affected were shoppers at physical stores.
I’ve had my CC number swiped a few times as a result of skimmers at restaurants: people who have a second card swipe that is used to catalog your account number for later use. It’s impossible to track who’s doing it. Your best bet is to memorize the 3-digit CVV2 number on the back of your card and physical scratch it out of the card with a knife. If people at points of sale ask for it, decline to do business with them. There’s no reason for POS people to have that number. That’s a newer measure put in place for online security.
Thank you for the valuable reminders.
