I guess I find this little story mildly humorous, but probably more reassuring.

The current quarterly promotion gimmick with Discover Card is currently a 5% cashback bonus for things related to travel. Hotels, car rentals, etc. So the gimmick is working in that I've recently been putting all my hotel, car rental, etc. charges on my Discover Card. And this month, I've been doing a lot of travel as it turns out.

So I returned home Saturday evening to find a message on the answering machine from Discover Card's Security and Fraud division. Seems like they were concerned with the sudden increase in travel related charges on my card. Hmmm....mebbe because of their promotion?

The amusing moment in the charge review was the question, "And you have a charge here from Southwest Airlines for...." "$5.00" I answered. "Right" the lady replied. "How do you only get a $5 from Southwest Airlines?" A couple of witty responses danced through my head, but I decided to be nice and say "Security Fee on a Frequent Flier ticket".

But in all seriousness, it's nice to know that someone's computer algorithm for detecting these types of things actually worked correctly.
