As a workaround on iOS, you could make multiple contacts for yourself with varying amounts of metadata, pick one to share from the contacts app and share it using AirDrop (only works if the recipient also has a Apple device, of course) Alternatively, use a QR code generator to generate codes containing whatever you want to share and store them somewhere on your device such as in a note taking app.
