Hi,

read today in a dutch newspaper that the radiation fom a smartphone could damage the magnetic strip and/or chip on a bankpass or creditcard.

On the other4 hand, I like the idea of carrying creditcard and n900 in the same pouch.

Would it help to carry the creditcard in a metal sleeve?

e: I'd be more concerned about n900's screen than credit cards chip when those two would be side by side in my pocket....

Honestly, the only 2 things that's ever stopped my bank cards from working are a. snapping them, or b. salt water (not good for the chip).

I'm sure some giant electro-magnet wouldn't do it any good, but a phone? Please!

Anyway I'd be more worried about what it can do to your brain if it can destroy bank cards

Eh, I seriously doubt it. You can stick a magnetic-stripped card in the microwave for a few seconds without frying it and that's a few thousand times stronger than anything your phone could ever put out.

A RFID chip however could be damaged, but probably not by a cellphone - Three seconds in the microwave however will turn it into a nice char spot on your card.

I haven't had a credit card fry on me from a phone and I have been using both and close to each other for more than a decade.

I have had hotel cards get deprogrammed though from a phone when kept together (I am talking same bag here not really close as in a pocket or case).
I guess it depends from the quality of the card.

A bank card is designed to last anywhere from 1 to 4 years of abuse in wallets, pockets, atm's, teller machines etc.
A hotel card is probably the cheapest available quality and pretty much disposable.

My credit cards suffers a lot due to my wife's shopping when compared to the radiation of 50 smartphones.

My stupid local bank keeps sending me cards made of some self-disintegrating plastic, that last only 6 months in my wallet... When I ask for a replacement they just send the next card with extended validity date, so now I have a cracked card that is valid until 2016. Idiots.

Dunno about radiation, but devices containing magnets (such as the N900) are a definite concern for the cards' magnetic strips. Best to keep them at a reasonable distance.

I remember seeing on Mythusters they trying to mess up the data on magnetic strips on cards with all sorts of magnets, and only on very extreme cases anything happened at all
