Do I need a QR code for proof of vaccination when applying for the Thai Pass?

When applying for the Thai Pass, you do not necessarily need a QR code for proof of vaccination. A paper card, such as the CDC vaccination card issued in the US, is acceptable, although it may lead to a longer processing time as it will need to be checked manually. Some users have mentioned alternatives, like obtaining a QR code through retailers like Walmart or printing a version with a QR code from their vaccination records.
