Scanning business cards at trade shows
Exhibition halls are loud, crowded and often without signal. The cards still need to be in your phone before the evening.

A day at the show
-
Between conversations
Scan each card as you get it. Recognition runs on the iPhone, so the hall’s Wi-Fi does not matter.
-
A pile at lunch
Lay several cards on the table, take one photo, and import it from your library: each card becomes its own contact.
-
Tag the show
One tag for the event keeps the whole day together; open it later to see only those cards.
-
That evening
Go through the tag, add a note where you remember something, and save the ones you need to iOS Contacts.
Faster than typing, without a lock screen in the way
On an iPhone with Camera Control, set it to Kardhaus and one press opens the scanner, even on a locked phone. The Lock Screen, Control Center and the Action Button work too.
Does it work in airplane mode?
What about cards in Japanese or Chinese?
