Modern smartphones consist of several systems, including the baseband subsystem, which controls the radio transmitter and receiver. This subsystem can function independently of the main operating system, allowing the device to seem "off" while the radio remains active.

Even when powered down, phones can enter a low-power state that maintains full transmitting and receiving capabilities. The screen turns off, and there's no detectable heat, giving the false impression that the phone is fully off. Apple’s “Find My” feature illustrates this well:

“Find My helps you locate this iPhone when it is lost or stolen, even when it is in power reserve mode or when powered off.”

As operating systems advance, it becomes harder to know when our devices are truly inactive. For those who prioritize privacy, the GoDark® Faraday Bag offers reliable protection and peace of mind.

Setting your phone to airplane mode only stops it from transmitting signals — not from receiving them. Even in airplane mode, your device can still log location data and store audio input through onboard sensors. This data can be quietly saved and transmitted later once your phone reconnects to a network.

For location tracking, the GoDark® Faraday Bag blocks incoming GPS and cell signals, stopping your phone from receiving the data it needs to record your location in the first place. No signals in means no location data recorded — and nothing to transmit later.

For audio surveillance, Mic-Lock® physically blocks your device’s microphone, preventing it from picking up sound at all. Without microphone input, even if spyware tries to activate audio recording, there’s simply no audio captured.

Together, these tools provide layered protection that airplane mode alone cannot match.

Mic-Lock is an audio blocker that prevents your device’s microphone from picking up sound by replacing it with silence. A Faraday bag is a signal blocker that shields your device from wireless signals (Wi-Fi, Bluetooth, GPS, RFID, etc.), preventing tracking, hacking and remote access.

Card Guard works by actively interfering with RFID scanners. When a scanner tries to read the information on your credit card, Card Guard emits a signal that disrupts the scanner's attempt to collect complete data.

This error prevents the scanner from accessing any useful information stored in your card’s RFID chip.

Instead of passively blocking signals like traditional RFID shields, Card Guard actively jams the scanner's ability to communicate with your card, offering a more robust layer of protection against skimming attempts.

This is the reason why Card Guard works whether you put it in front, middle or back of your credit card stack.

If you are looking for a complete privacy solution, then yes. If you want to block EMF signals to prevent tracking, hacking or remote data extraction, a Faraday bag is the right choice. If you are worried about audio surveillance, Mic-Lock is essential. Lastly, Card Guard will protect your wallet from RFID skimming.

A Faraday bag blocks signals like WiFi, Bluetooth, GPS, and cell signals because it creates a shield that stops electromagnetic waves from passing through. However, it does not block sound because sound travels in a completely different way.

Electromagnetic waves (like radio signals) travel by means of alternating electric and magnetic fields, which Faraday bags block by redirecting them. Sound waves, on the other hand, are mechanical vibrations that move through the air and other materials. Since a Faraday bag is designed to block electromagnetic energy, not physical vibrations, it will not prevent sound from passing through.

No, many apps and spyware can secretly activate your mic without your knowledge. Mic-Lock physically blocks any microphone input, making unauthorized recordings impossible.
