Tattoos Barcodes and QR Codes.... oh my!

So I already have one tattoo and it is of a traditional AA symbol the circle and the triangle with a AA in the middle. The triangle is in the circle for those of you not familiar with it and spanning off of both sides are wings, as in the freedom that AA has shown me I can have if I stay sober each day. The best explanation of the circle and triangle I could find says this:

The Sobriety Circle & Triangle Symbol, is the symbol used by Alcoholics Anonymous. The equilateral triangle represents the three part answer - unity, recovery and service - to a three part disease - physical, mental and spiritual, while the circle represents wholeness or oneness.

The body should be triangular, stable, the mind circular, open. The triangle represents the means for generation of good energy, and is the most stable physical posture.

The circle symbolizes serenity and perfection, and the source of unlimited potential. Together they represent the perfect union of mind and body.

Then underneath it I have a saying that I need to live by that is "Live and Let Live." And no for those of you who have actually seen it, I did not get that from The Postman starring Kevin Costner. I got it from AA where I found it says "Live and let live" reminds us that patience and tolerance of others is our code. But basically if you know anything about AA I think it basically means keeping my side of the street clean. I also found where someone wrote this regarding the saying,
"Judge not lest ye be judged. Do not look to criticize faults of others, always look for the good. God says Vengeance is mine - our role is to love one another." Any way I look at it I know I have to live my life the way I need to live it to stay sober and that acceptance is the key here. I cannot change anyone from who they are or for what they choose to do. I can think to myself why is this bothering me and how can I change myself!

Basically this tattoo has a lot of meaning for me and I always told myself if I got a tattoo it would have to have significance in my life. So in that I only have one tattoo so far and not because I cannot find anything of significance to get a tattoo about but that my wife has a disliking for them and she said if I ever got another one, well it was over. Well I want another one and let’s face it folks things are no smelling like roses on my side of the street right now.

So I am interested in a code tattoo, specifically a bar code or a QR code tattoo and I want to know if anyone has one? Also is it scannable? How long have you had one? Has it become harder to scan over time if it was even scannable in the first place? What information do you have stored in it if anything? Or does it just spit out nonsense?

I am in IT so I think QR codes or bar codes or any codes for that matter are becoming more and more prevalent in our lives. So if you have any answers to my questions by all means leave me a comment or point me in the right direction for some good answers.

Thanks

Later... I am off for pancakes! :)
