Sharing cards with another Haystack user is fast & simple.

Tap the 'share' icon at the bottom right of your card, and choose the 'QR Code' option.

Once the QR Code is displayed on your device, ask the recipient to open the 'scanner' mode in their Haystack app and point their camera at your QR Code - your card will appear in their Haystack instantly and their card will be exchanged back to your Haystack - magic!
