While neodymium magnets are powerful, your electronics ARE SAFE as the magnets will not affect most electronics; exceptions include very old monitors or TV screens. It takes a very large magnet to affect an older hard drive, and the magnets we use simply aren’t that powerful. Let's break it down:
The magnets will not affect your phone or phone calls. In fact, magnetic smartphone mounts are quite popular– here's a video that addresses this concern.
The magnets will not affect vehicle keys, USB sticks, memory cards, CDs, DVDs, digital cameras. Here's a video demo of other daily things magnets do not affect.
The magnets will not affect your credit cards. It would take very deliberate, repeated swiping to possibly affect the magnetic stripe. A hotel key card (which gets recoded often) can be easier to erase, but after months of testing (and staying in hotels while using the ModWallet), we haven't seen any issues. Your cards are more likely to be affected by scratches or bends than by magnets– and on that front, the soft-touch TPU material of the CardSleeves does not cause scratches.
So, what IS affected by magnets?
Use caution near watches and clocks that have metal gears. Magnets will keep metal gears from functioning properly – magnets do not affect digital clocks. You can easily reset your watch if this happens, though it's unlikely since they won't typically be coming in close contact.
Some hearing aids may react or become damaged if magnets are deliberately placed on them. Use caution if you have a pacemaker or other implant that is sensitive to magnets, and follow your doctor's advice.
Older computer monitors and TV screens can also be affected by magnets.
