Since iOS 13, Apple has changed the method of saving the Vcard, in other words the contact details that are saved in the iPhone phonebook from the digital business card.

Once the Vcard has been opened on the iPhone :

1. You now need to keep your finger pressed on the portrait photo or the location of the photo with the contact's initials if they don't have a photo.

2. This will open a menu offering you the option of saving the contact by clicking on "New contact" or "Add to existing contact".

3. Click on "OK" on the right to confirm the registration.

4. To exit the vcard once it has been saved, click on the "OK" button on the left.

**And now your contact is saved on your iPhone!
