I just placed an online order for some baits, and it made me think about posting this tip here...
With the increasing number of spyware programs attacking our computers on a daily basis, I am always protective of my credit card number. You can never be certain that somebody isn't watching your keystrokes, looking for a string of numbers that resembles a credit card. Therefore, I never type the numbers in the correct order. For example, my card has 16 numbers in four groups. I will type the second group of numbers first, then click the curser back to the front and type the first set of numbers. (The keystroke logger won't log the mouse click.) Next I type the last set of numbers, followed by the third set. If any malicious program is watching me, it may have the numbers, but they will be in the wrong order.
