DropCard does not have any direct access to any of those items, so Settings does not display DropCard in the application list (the last group).
Why is the recipient's iPhone not showing up in AirDrop?
Many people that use AirDrop are set for "Contacts only". If you have just met them, you probably are not in their current contacts.
To solve this "chicken and egg" problem, have the recipient temporarily set their AirDrop to everyone
(see https://support.apple.com/en-us/HT204144).

Afterwards, please be polite and remind them to set AirDrop back to "Contacts only". |
