Eurobricks members Ras74 and Superkalle have some great pics of the actual Series 2 Collectible Minifigures next to their corresponding bar codes.

The bar codes seem to largely match those we've found on
bricks.inof.de, with some subtle differences. Between these pics and the
pdf cheat sheet, European collectors won't have any difficulty finding the figs they want.
