Description

Travelers can now expect to check the increased random use of trace explosive detector technology in areas where TSA recently conducts screening such as security checkpoints and checkpoints queues as well in the areas such as checkpoint queue and boarding areas. The swab is placed inside the ETD unit that analyzes the content for the presence of potential explosive residue. To ensure the health of travelers, screening swabs are disposed of after each use. Since it will be used on a random basis, passengers should not expect to see the same thing at every airport or each time they travel.
