Cellphones, once a rare and expensive commodity, are now a necessity for many people. Children and teenagers take cellphones to school, and adults use their phones to conduct business away from the office. Some places, such as schools, see cellphones as a distraction. Many schools ban cellphone use, and they monitor students who enter the building with a metal detector. Airport security checkpoints also employ metal detectors to help officers find potentially dangerous objects, like knives or pepper spray. If you do not want a metal detector to find your cellphone, it is possible to shield the device with your hand.
Cup your hand around the cellphone. Ensure that your hand covers all parts of the cellphone. The metal detector will locate any uncovered parts.
Press your hand firmly against either side of your body to form a shield around the phone.
Walk through the metal detector portal as quickly as possible. When walking through, keep the cellphone away from the side of the metal detector.
