Potential Harm From Magnetic/Copper Bracelets?

[WhyNot]

Oh well, turns out the damn thing gives me a rash anyway! :smack:

That’s just the demons being driven out of your system.

Most of the magnets you’re likely to encounter in your day-today travels will be insufficiently strong to damage high-coercivity bank cards.

Youre just wrong. Ive destoyed so many cards with just a simple fridge magnet so many times its not even funny.

Maybe you should stop waving refrigerator magnets over your cards?

[Q.E.D]

Possibly, but unlikely:

In practical terms, usually low coercivity magnetic stripes are a light brown color, and high coercivity stripes are nearly black; exceptions include a proprietary silver-colored formulation on transparent American Express cards.** High coercivity stripes are resistant to damage from most magnets likely to be owned by consumers.** Low coercivity stripes are easily damaged by even a brief contact with a magnetic purse strap or fastener. Because of this, virtually all bank cards today are encoded on high coercivity stripes despite a slightly higher per-unit cost.

Well how the heck am I supposed to stick my credit cards to the fridge then, huh?

It is kind of funny, actually. You’d think after once or twice you’d stop doing it!
