You don't want to write it down because you are afraid the paper will get wet and all your funds will be lost?

Here's another solution:

These beads can be purchased by the hundreds for under $5, there is no reason why anyone should be losing their credentials. You can just make some jewelry most people aren't even going to pay attention to. I think people would be more likely to find interest in a paper with all them strange numbers than a poorly made craft.

You can stash it away, bury it. These beads are sold in metal too!

Colors can be used to identify when a character is capitalized if necessary, the same goes with numbers. No reason to use actual numbers when they sell different color beads too.

You can memorize what the colors mean or even make the decoding of the wallet part of the necklace in design.

Just make sure to get a very strong string to keep the beads together because I wouldn't want to ever have to face the challenge of having to put a broken wallet back in order.
