We already HAVE the vaccine passport system, need to expand it.

In LA county, one of the providers for vaccinations provides one with a QR code which can be saved on your phone.

When the QR code is scanned, a page pops up with your name, age, address, date of vaccination and even who gave the shot.

No silly paper card, easy to falsify... no chip in your body lol...

Let's have the CDC set up a nationwide system, email or snail mail all recipients their own QR code or directions how to access it. It can be done.

QR scanners linked to the CDC at movie theaters, airports, cruise ships, malls, etc...

Those without a phone can carry a plastic card (like a VISA) with the QR code printed on it
