My one card got hacked over the weekend. Someone tried to use a fake card at a gas pump for $1.00. It was denied & CC company called me. Had to close account & get a new account/card. I was told there are people out there now making fake cards! So watch your monthly invoice.
What would be best to use on line is get 1 card just for on line use. Use it for nothing else. You can also put a fraud alert on your account that purchases only get delivered to yuor address. That way if someone tries to send items to another address the purchase will be denied.
