In today's world, our phones, cards and even keys are constantly sending out signals. This is convenient but it also leaves us vulnerable to tracking, hacking and theft. Faraday bags are designed to block these signals completely creating a secure shield around your devices. But how can you be sure a Faraday Bag really does its job? The good news is you don't need a lab full of equipment- with just a phone or a credit card you can easily run simple tests at home to prove your bag is working.
The Phone Call Test
Place your phone deep inside the faraday bag and seal it fully.
Call the phone from another device.
If the bag works, your call will not connect, and the phone will stay silent.
The TXT Message Test
Send a txt to the phone while its inside the bag.
The message won't be delivered until you take the phone oat of the bag.
GPS Tracking Test
Open up a tracking app like "Find My iPhone" or "Google Find My Device"
Put your phone in the faraday bag.
The location should freeze or go dark, proving GPS is blocked.
Wi - Fi & Bluetooth Test
Connect your phone to Wi Fi or pair it with Bluetooth headphones.
Place your phone in the faraday bag.
Connection will instantly drop.
RFID / NFC Test (for wallets and car keys)
Try tapping a contactless payment card or car key fob whilst inside the pouch.
The payment won't go through, and the car won't unlock.
Final Thoughts.
Faraday bags are an easy effective way of protecting your privacy- but only if they actually work. By running a few quick tests yourself, you can have peace of mind knowing your devices are truly shielded. Whether you're a business professional or just someone who values privacy, verifying your bag gives you confidence that your communications and data are safe.
