How a card comes in
Scan it
Photograph the printed card with your phone. The reader transcribes it, the validator checks every hand, and you correct anything it misread, line by line, with the photo beside you.
Scan a cardOr type it
One hand per line: name | section | points | tiles, with the tiles written the way the card prints them and a letter for each color: FFFF 2A 0 2A 6A DA*4 DB*2.
Say whose it is
A card you made up is yours to share. A published card stays private to you, and you acknowledge owning the printed one each time you sit down with it.
