The My Bindle app supports uploading QR records that use the Smart Health Card (SHC) format.
Below are some links where you can access some of the most commonly requested or used SHC QR codes. If you don't see your provider in the list below, you can see if it is listed in this registry of providers who are using the SHC format. If you have a SHC QR code and you don't see yours listed in the app during the import process, you can use the option to select "Other Smart Health Card" and it should import.
If you search for the website of the government entity, pharmacy or provider you should hopefully be able to find a link where you can download a QR code that contains your specific vaccination information. It will likely ask you to verify your information including name, date of birth and possibly even social security number.
