The 5 lines of code are yet to be deciphered
Yeah, I read the article. ;-) LOL
It looks like they suspect it may have something to do with horse racing.
Which leads me to...
I'm too well known and my prints are on file all sorts of times. I also tend to carry identification with me, simply because it's habit to carry my wallet - though I do not always carry a phone.
But, assuming none of those were true, they'd have a heck of a time trying to figure out what was going on if I died suddenly. I've frequently got pockets full of the weirdest of things - including paper with stuff that makes sense to me but would make no sense to anyone else looking at it. I make quick notes to myself that aren't really notes but serve to remind me of something.
Like, if I saw two geese flying north for the season and wanted to tell my wife, I might write down '2GN' That'd be enough for me to remember and the act of writing it down helps solidify it in my memory so that I don't really need the paper at all later on. I always have a pencil and some paper, usually a tiny notebook.
Alas, they'd have no trouble figuring out who I was and deciding my cryptic notes were of no value. I'm pretty easy for 'em to identify.
