Re: Quick Fire Questions (A Place to Ask and Answer)

The wiki article links to a "booster bag"

Quote:
The booster bag can be an ordinary shopping bag, backpack, pocketed garment, or other inconspicuous container whose inside is lined with a special material, typically multiple layers of aluminium foil.

An item is placed inside the booster bag (effectively a Faraday cage). Electronic security tags inside the bag may not be detected by security panels in the detector antennas at the store exit.

Line the inside of a hat or his jacket with aluminium foil?
