Does cash show up on metal detector in airport?

Answer 1

Cash can sometimes show up on metal detectors at airports, but it typically doesn't trigger alarms like metals do. The quantity of cash may influence detection; larger amounts, especially in coins or metal-based currency, may be more noticeable. However, most airport security scans focus on detecting weapons and explosives rather than cash itself. Additional screening may occur if security personnel have concerns about the source or amount of cash being carried.
