Hello, I travel very often from Ney York to Fort Lauderdale, sometimes 2x a month. I have already answered this question on many of the different forums. Let me assure you that the tape does come thru on the scanner. I was pulled over once and my scan was still on the screen. I saw a ghost image of my whole body. I saw 3 white highlights on the screen. One was my watch, the second was my ring on my finger and the 3rd was a half horseshoe halo arround my head that was my tapes that I wear on the back and side poly. Now remember it could of been the poly that showed up and not the tape. No big deal. The officer just examined my hair closely and let me go thru. If he would of asked I would of told him I wear a piece. I am sure I am not the only one. The biggest laugh is that my passport picture is still me before I started wearing and then they get to see me in person with the hair peice. Here in Canada the passports are good for 5 years so in December I get to take a new picture, HA!HA!. I have had a couple of agents ask me whats up , and I told them I wear and he was shocked because he would of never been able to tell.
