Mini-CD would be too big for this size, wouldn't they ? Something similar to a credit card would fit the bill and could look gorgeous.

The issue of course would be that there aren't cards of that format that can store the amount of data required, but maybe with a bit of fantasy a micro-sd card could be embedded in it.

Yeah a minidisc is 64mm, I couldn't find the exact measurement in the README and can only dig so far on my mobile but even just eyeballing it and measuring a deck of cards it would be a lil too big.
