A lot of bars and restaurants are making people show their vaccine cards to get in now. There are also digital versions for your phone that have a QR code they can scan. Or, I guess this option might be SLIGHTLY more convenient.
A 22-year-old in Italy is going viral after he got a QR code TATTOOED on his upper arm that links to his vaccine status. He tested it out at a McDonald's that requires proof, and it worked.
He says he also did it because he just wanted a tattoo that was UNIQUE. His parents aren't thrilled though, and told him to stop being so impulsive.
