My comment when I saw this is that they should really have the QR code point to a redirectable URL. If their address was compromised for some reason, it'd be a pain in the ass (perhaps literally) to have it changed.
Vegas was a great city and to have this adds to the Vegas life experience. I was wondering what will happen if they need to change the address for some reason?. I think they need to do the tattoo again. Even the greatest tattoo artist won't be able to edit QR code on skin. Looks good on the strippers though. It adds personality and attracts customers. Great idea but the stripper should look also.
In the article it says that they are using
temporary QR tattoos. Changing them is not a problem.
But it is always great to see new and innovative ways to use Bitcoin. There are dangers too. When you are doing the payment with your phone, someone could take your phone and empty your wallet.....
