@tomas.ztkeco: Can Foil Hide a Phone through School Security inspection? 📱 We simulated a student entering school security with a mobile phone wrapped in aluminum foil inside a bag. Then the bag went through an X-ray scanner. 📱 The phone was still detected 🧲 The foil did not prevent identification 🧠 Different materials remained clearly distinguishable on the X-ray image Even with foil wrapping, X-ray scanners can still identify concealed electronic devices. Real test. Real result. #schoolsecurity#xrayscanner#airportsecurity#securitytechnology#xrayimaging
