What is a Faraday Bag?

A Signal Blocking Bag, also known as a Faraday Bag or an RFID Blocking Bag, is a bag designed to block radio wave signals, particularly signals from wireless devices such as cell phones, Radio Frequency Identification (RFID) tags, Bluetooth devices, car keys and GPS receivers. These bags are lined with a special material that blocks electromagnetic waves, preventing signals from entering or leaving the bag.

Signal Blocking Bags are used for privacy and security reasons. In a Faraday Bag your cell phone can not be tracked or remotely controlled. An absolute must for your privacy. RFID Blocking Bags are also used to protect RFID chips on credit cards, passports and ID cards from unauthorized reading. This helps reduce the threat of identity theft as criminals usually use RFID scanners to steal personal information from such cards.

Signal Blocking Bags / Faraday Bags provide an easy way to block wireless signals and ensure security and privacy.
