The other day I got a call from my credit card company. They thought that I had my card stolen (I guess) because a couple of purchases I did. I filled up on gas twice in the same day (driving from London), which isn't something that I normally do. I just think that it's interesting that 2 purchase tipped them off that something might be "up". They must have some kind of a learning algorithm for each and every customer. I wonder if it's similar tech to how my spam filter learns..
Before Laura and I went to Europe I made sure that I called my CC co. and bank to let them know that I might be making purchase from afar. Everything went smoothly. Maybe it's like the rock that protects me from tigers, or maybe it really made a difference, but I'll do the same thing next time I go away. ;-)
