Oh btw, might have been good to tell you guys, I live in Sweden, in which we don't really have social security number.
We have our birthdate + four numbers, and that's not that hard to remember.Social security #? 
Would be pretty fitting with the whole barcode theme, but I dunno really.
Credit card number. And PIN afterwards.
Or maybe just some meaningful date to you? Something personal, not only the release date of the new album.
You can also encode some message, like M45U.15.1337.4ND.4W350M3

Well, since the release date IS something meaningful for me.

But yeah, I know what you're saying. But to be honest, I don't have many dates that really mean something to me, I can only think of Masu release date, release fests and my birthday.
Hm, maybe the date they released their webpage for the first time, or some date on where the whole thing began.
I'd say get the Trinity coloured blue instead of the grunge in the barcode and change the numbers to your SIN. That way when you need it you don't have to carry your card and can just look at the tattoo. =P
I'll see what I'll do with the trinity logo.
Don't live in Canada, so I don't have a SIN.
