I made this credit card wallet from bubinga and ash. It uses two rare earth magnets to keep it closed, ash did not do well with the thin walls around the magnet. But, it still works, so…

Look great, but I wouldn’t use it with credit cards if I were you….....
Most all major manufacturers of rare earth magnets post the following warning:
“The stronger magnetic fields can be hazardous to mechanical and electronic devices, as they can erase magnetic media such as floppy disks and credit cards, and magnetize watches and other clockwork mechanisms and the shadow masks of CRT type monitors.”
I’ve even seen “credit card erasers” being sold that are simply four RE Magnets placed in a swipe device.
Use it for business cards – they can’t get erased! ;-)

I made a prototype wooden wallet last year, and put a rare earth magnet on one of the sides. The idea was to use a strip with another magnet or a piece of metal to keep the cards in.
Some weeks ago, a brand new credit card was erased, and a couple of days after that, my perfectly working debit card was also erased.
I’ve removed the magnet just in case, and now I’m searchig for some alternative.
The magnet I used was a 2mm thick, 5mm diameter round magnet. I had problems with the cards after maybe two months (but one card seemed to be erased in a matter of days if not hours)

Change “credit card” to business card and the magnets now seem like a good idea.

Thanks for the advice about the magnets. I didn’t even think about the affect it would have on credit cards…guess I’ll have to figure something else out for future iterations :)
