Using the Bindle app to gain an entry pass for the White House Correspondent's Dinner on Saturday, April 30 requires you to enter proof of vaccination completed by April 16 AND a negative antigen COVID test completed on the day of the event. This can include an "at-home" test including the ones distributed by the federal government available through the US Postal Service.
After creating a Bindle account, you will want to go to the "My Certificates" link in the app and enter your vaccination information, making sure that you create a certificate for EACH vaccination shot you've received. In other words, if you initially received a two-dose regimen and subsequently received a booster, you would want to create three certificates, one for each shot.
Finally, on the day of the event you will need to take an antigen test and include proof of a negative result. You can either take the test at a lab/testing center or an at-home test.
If you're taking an at-home test, it should look something like this after following the instructions on the test:
A single line on "C" means negative. If there are lines on each "C" and "T", even if they are faint, then that means the test is positive and you should not attend the event.
After getting your negative test from either the lab or on your at-home test, go to "My Certificates" in the Bindle app and click the (+) button and click the button to enter a certificate for "COVID-19 Test Results" and enter in the information for the test including a screenshot/photo/upload of the negative test result. Make sure when you're asked for the date of the test that you enter 4/30/2022 or else you will not be able to claim an entry pass for the event.
The negative test certificate, along with the previously entered vaccination certificates should allow you to go to "My Passes" in the Bindle app, search for the White House Correspondent's Dinner and successfully claim an entry pass to the event which you can show upon entry.
