I'm planning to make some cell phone carriers with a magnet closure, namely, round ms34n nickel magnetic snaps. Does anyone know if these interfere with the inter-workings of a cell phone? And, do you know if they would mess up a credit card?

Thanks for your knowledge!

there are leather pouchs that have have magnets on the flap, i have one and my cell is not affected

Check one of the phone carriers. I have a smart phone and when I bought it my carrier suggested I not put in the pourse I was carrying due to magnet. I asked about magnetic flap on ase and he said the magnet is incased in leather. May not hurt to call a local shop and ask.

They definately affect credit cards , found out the hard way when I used a new bag while on vacation.... it wiped out the mag stripe on the back.... none of my cards would work. Did I mention I was on vacation..... what a disaster!
They can effect some cell phones, as they are more than just a phone .. many have computer chips that will be adversley effected ! I would use velcro or some other closure method.

I know magnetic closures on purses effect motel room keys! Sucks!!

Thanks for that...never would have thought about it until too late probably!

yep...found that out the hard way too...sigh

Hmm, Thanks for the information. I didn't even think about any of these.

They effect computer flash drives too if you carry one in your purse

Wow, all those things that are affected by the magnetic clasps!!! I do know I was told that eel skin wallets affect the magnetic strip on credit cards....I had to change my credit card a couple of times before the bank inquired about the kind of wallet I was using.
