Bank of America has "shop Safe" numbers. You can create a seperate number for each transaction and set the $ maximum as well and the expiration date of that number. Interesting enough I had a fraud situation two weeks ago. They tried to use one of my depleted shop safe numbers and the credit card company called me to see if it was me. That transaction was the day after ordering vaping supplies. hmmm
I too had an incident about 10 days ago, also after placing an order for PV stuff...within a few hours I was emailed by my CC company Fraud Dept. It appears my card was hijacked, and has since been shut down and replaced with a new one. I know where this happened, but at this point can't say if it was vendor...or billing company they use. CC company is investigating, this one was easy to pin down..because I had never used this card online before, and had not used at all for months, so to have several fraudulent charges with in 3 hours of using it for this purchase...not rocket science. I will update when I get more info from CC company. This happened on 1-10-11 if that helps anyone.
