HOW DO CELL PHONE BANS WORK AT LIVE PERFORMANCES?
Jack White, the former lead singer of the White Stripes, announced recently that his upcoming tour will be 'cell phone free'.
White plans to have his fans lock up their phones in Yondr pouches as they enter a concert venue.
The pouches function similarly to theft-proof tags on clothing items in department stores.
They cannot be unlocked inside certain areas.
If users need to make an emergency call they'll have to step away from the venue to access their phone.
Highlighted in green is the area in which cell phones can be locked and unlocked
The encircled area will be 'cell phone free', meaning people in the area will not be able to unlock Yondr pouches holding their cell phones
