Why does Samsung have no integrated app (with Samsung Pay) to store your QR code, like boarding passes for flights and trains? A feature that Apple already has for years.
I don't know where I can request this feature, since Samsung has no email or other direct way of contacting.
You can send your suggestion directly to our Developers through the Samsung Members app on your phone. Just go to Samsung Members > Get Help > Send Feedback.
Hope this helps!
