There are several programs 1. Clip in the head of the pants test, do not reveal, the head of the pants have to be metal, if the ring, you will show him, he can only check out is the head of the pants ring 2. Put on the inside of the shoe side test or directly step on the soles of the feet, generally do not have to scan the shoes, there is basically no 3. This is more adventurous, act opportunistically, have seen other people with the exam loaded pen, eraser, pass bag it, transparent, the phone, pen, eraser, pass into a transparent bag, pass blocking the phone, over the metal detector when you hold the pass side of the punch. Cell phones, pens, erasers, passes into a transparent bag, passes blocking the phone, over the metal detector, you hold the pass that side of the teacher rushed, he can only see the pass, and then you check the smooth passage of this depends on the situation, the check if it is very strict have to be careful. The Internet said what tinfoil wrapped cell phone, I have not tried, I suggest that you do not try, failure is over. The most important thing is that the face is not red, not gasping, not nervous, must look at the situation, see the opportunity to act, personally recommended 2, I feel that the most secure.
