I think you are better buying a hat on Fortnite: you’ll look really cool in-gameGosh. Just downloaded the appp and created an account. It's actually found my seven "Certifications with no e-cards". Clicking on one of those shows no further data (date, location, etc.). But this obviously exists on the PADI database.
However, it is ever so helpfully suggesting I donate to the PADI organisation by "Purchase eCard". Why on earth would I need to do that as it show I'm certified? Is this like buying a hat on Fortnite?
And yes, I've photographed my cards should I ever loose them.
Maybe you just gave away a business idea: accessories for your diving avatar. I want a Rudolph hat on my cert and matching brown gloves.
