They hand you a business card right after the photo you took together. By the time you get home it is in a pocket with many others, and the face that goes with it is already fading.
Nexus Contacts lets you add the card to the person you just met. Open their page, choose “Add their business card”, then “Take Photo of Card”. The app reads the card on your phone using Apple’s text recognition.
What it found
The next screen shows you what was “Found on the card”. It offers First Name, Last Name, Company, Job Title, Phone, Email and Website as separate rows, and you tick the ones you want. The screen’s own words: “Tick what you want, and correct anything the scan got wrong.” Nothing is added until you choose.
The photo of the card is saved with the person either way. If the scan comes up empty you see “No contact details were recognised on this card. The card itself is still saved.” If the read fails, you can tap “Read Card Again”, which re-reads the saved photo.
If that person is already in your phone contacts, the app tells you so and asks whether to “Link to It” or “Create a New One”. If Contacts access is off, nothing from the card goes into your phone contacts, and the card is still saved with the person.
It works on one person at a time, from their page.
