Life lesson - In case you're not aware

I like the fact someone is looking out for us with all the breaches going on. Just last month Barclays called me (text from fraud unit) that they had denied a catering bill in Chicago for $235. I'm in California. So they cancelled my card which by the way had a zero balance since last year and sent me another with a new acct number. I asked them how my acct could have been compromised when not being used. They really didn't have an answer. The same card was compromised over 2 years ago at a Loves gas stop, but I know how that happened. So when we travel we use credit cards not debit and some small cash.
Ever since the Target mess, I monitor our credit card accounts every few days, I don't wait for the statement.
