Why QuantaCase
We build around first principles—time, distance, and orientation—and keep the shell antenna‑friendly so your phone doesn’t work harder than it needs to.
Shielded Speaker Aperture
A visible, conductive screen maintains the protective layer across the earpiece opening for better continuity.
Antenna‑Friendly Shell
No large metal plates, magnets, or stacked cards that can obstruct or detune antennas and increase transmit power.
Ultra‑Thin, Daily‑Carry
Purposefully slim to avoid bulk that encourages misuse and to stay compatible with mounts.
Single RFID Slot
One slot for essentials—keeps the cover light and helps you use it properly instead of leaving it open.
Teaches Better Habits
Clear guidance printed and online. The case is a reminder: cover toward you for calls; cover behind for texting.
How it works
QuantaCase focuses on directional reduction. You get benefit by how you use it.
On a call
- ✓Close the cover so the shield faces you.
- ✓Use speakerphone or an air‑tube headset when possible.
- ✓Keep calls short; text when practical.
Texting & browsing
- ✓Flip the cover behind the phone so the shield sits between your hand and the device.
- ✓Keep the phone off your body when connected. Use a bag or surface instead of a pocket.
- ✓Avoid accessories that cover antennas or add magnets/metal plates.
Why no wallet insert?
Extra cards can block antenna areas and tempt you to leave the cover open—defeating the purpose. We keep it lean for proper orientation.
Reality check
No case blocks all RF energy. QuantaCase helps reduce exposure by encouraging better habits and orientation while staying antenna‑friendly. Distance is still your best friend.

Questions, answered
Does QuantaCase block all radiation?
No. No case can block 100% of RF energy. QuantaCase focuses on directional reduction by placing shielding in the cover and encouraging better distance/orientation habits.
Will it weaken my signal?
The shell is designed to be antenna‑friendly (no large metal plates, magnets, or stacked cards). The goal is to avoid forcing the phone to transmit harder.
Why avoid magnets and metal plates?
They can obstruct or detune antennas and create hotspots. QuantaCase avoids them by design.
What's the safest way to use a phone?
Time, distance, and orientation. Keep calls short or use speakerphone/air‑tube headset; keep the device off the body when connected; keep the cover between you and the phone.
Is QuantaCase a medical device?
No. QuantaCase is a consumer accessory that encourages lower‑exposure habits. It is not a medical device and does not claim to prevent disease.
