----- Tom was an avid collector of antique train sets. One morning while scanning his e-mail, he noticed one from an online auction site from which he purchased a good part of his collection.
The e-mail had the familiar logos and graphics Tom was accustomed to seeing with a tempting message that he could purchase a 1938 Lionel caboose for less than $50. The message was irresistible. Tom provided his credit card number and shipping address. The site also asked for his Social Security number. Not thinking twice, Tom entered the nine digits.
