What is a good way to keep track of your credit card transactions, to reduce likelihood of fraud?
One trick is to make all purchases end in a particular number of your choosing, say "3". From now on, all restaurant meals,gas purchases, and anything in your control, end them in 3. When you glance at the bill, you can skip these charges, and look carefully at the rest. It's not 100%, as you couldn't easily impact supermarket charges and many others, but it's half of my routine charges.
