InfoShare allows you to share just the information of a contact you want to. Share via QR code(anyone with a QR reader or iOS11 can use the camera app), AirDrop, email or text. InfoShare also gives you the ability to add contextual information, so your new connections will know where and you met. InfoShare is also platform independent so contacts are also shareable to non-Apple devices.
IMPORTANT Note
**To save the shared contact the receiver needs to hit the save button after they tap the contact information on the camera screen.
