In yet another episode that will go down in the list of embarrassments for Apple, its new-fangled titanium Apple Card credit card can apparently become permanently discolored if it makes contact with fabrics like leather and denim. Given that many users will keep the card in a leather wallet or even slip it into a jeans pocket, the revelation appears to beggar belief that it could be so impractical to carry.

Ha! Ha!
I never get tired of articles that knock Apple.
They did what? They painted a titanium card? Glad that the moron behind this decision is leaving Apple for his own startup.
Titanium does not corrode, is non-toxic, and needs no goddamn paint. Give it a good surface finish - polish or nice matte, and leave like that.
Apple - "You're storing it wrong"
I believe this is the nature of titanium, the only way to keep it looking like new is to use an oxidizing process in which it comes out colored, like water bottles from Taic, and even then the processing only serves to mask discolorations.
@S.Yu - You need to make fewer excuses for this crap company OR go back to school for Chemistry 101.
Titanium does not rust/corrode. That's why it is used in the harshest environments.
The card is obviously not really made of Titanium. Given that Apple always uses cheap materials & components in its products, you wouldn't be able to afford to own the credit card if it is made of Titanium! It may not be that expensive as a material... however its the cutting/machining or casting or polishing that is expensive because it is so strong and tough!

Titanium actually does corrode, the only reason it lasts in the practical sense is that TiO2 does not corrode, OTOH TiO2 is much softer than Ti and the thin film of TiO2 on that forms naturally on Ti wears unevenly with use, in turn new TiO2 forms unevenly. On top of that TiO2 is much more reflective than Ti, so the unevenness of the layer of TiO2 even on the nanometer scale is visibly noticeable, that's why titanium products easily discolor.
