All of you mouthy wise-guys have missed it. The real problem with WAL-MART is that they are into RF Tags. RF Tags are those little white plastic things about 1 X 3 cm which are attached to merchandise. Or hidden in things you buy. When you check out, the computer correlates the RF Tag with your credit card number. As you walk around town in your new WAL-MART Chineese $10 sneakers, with the RF tag hidden in the heel, you can be tracked. Although the range of tracking is limited to a few feet, eventually anyone who is interested will know where you go. Or did you give those sneakers to your mother-in-law?
