A smartphone constantly emits electromagnetic radiation, at least when it is turned on. Even when turned off, mobile phones like iPhones allow location tracking when turned off. But What if we wanted to make sure the phone stopped transmitting completely? Covering it in foil is 100% effective, we’ve seen it first hand, but there’s a lesser-known accessory that works better: the Faraday pouch.
The case is an almost essential accessory for a cell phone, even if this case is not permanent: there are those who temporarily put the phone in a sock, in a fabric bag or, as in the present case, in a Faraday bag. It seems like an unusual accessory, but the truth is that they are more popular than it seems. And they allow a large number of uses.
Faraday’s sleeve nip wireless communication in the bud
Michael Faraday was a British researcher and scientist specializing in studies of electricity and electromagnetism. As a result of this research, Faraday created the cage that bears his name, a demonstration that A metal cover can insulate anything hidden inside from an electromagnetic field.. And this also serves the electromagnetic radiation that a smartphone emits and receives.
Faraday sleeves use the same cage principle to create an insulator that prevents data transmission and reception from any electronic device found inside. Usually it is a kind of fabric envelope made up of several layers which, once they house the mobile, literally make it disappear from the map.
There are different types of Faraday muffs, all promising the same benefit: cutting off communications from a smartphone (or other electronic gadget). There are envelope-style cases, shaped like folders, for mobile phones, suitable for holding a tablet and even There are Faraday covers with transparent window
Faraday sleeves have different uses. For example:
- For activities where confidentiality must be guaranteed. It is enough to distribute a Faraday case so that once the visitor places the cell phone inside, the company ensures that he will not be able to share any secrets.
- To avoid distractions without having to switch to airplane mode. Putting your phone in its case may be more convenient than taking it out and turning it back on in airplane mode.
- To force disconnection. It’s impossible for them to be careful at dinner time? Let everyone put their cell phone in the Faraday case and that’s it.
It may seem like an unusual accessory, even delicate given the ease of anonymizing any smartphone, but the truth is that it is widely used. Its price is quite affordable and does not hide some of the uses for which it is used: it is common to see how cases are promoted to block access to phones via NFC and RFID; thus preventing the suspected theft of contact data, such as credit card data. Something as absurd as it is of little use: Simply disconnect wireless connections or put your phone in airplane mode.. Or, directly, use a cell phone that is not a smartphone, much safer.
