I’ll echo Gorramshiny and say that QR codes aren’t really a good solution, though my issue is less with phones coming out at games (I actually would support more phone integration, honestly, since it’s a much easier way to maintain the “live document” element of the ruleset; could do item-DB and rulebook as a phone app to just DL all of it and push updates through the app), and moreso with QR codes requiring an extra step compared to just reading a card.
As a Coord, I am 1000% behind getting card printers, but not because of the amount of work it is for Coord marshals to write the cards but rather ensure consistently written cards, mechanics, etc while keeping them legible. I’ve got tiny handwriting and use draftsman’s script (so that it’s legible and easy to read), but I know a lot of Coord marshals don’t have that skillset, which can make it extremely hard to write out extended mechanics and descriptions on the tiny area that the 3.0 cards allow compared to the 2.0 cards (7 rows on the back for basic, proficient, master, and PFA mechanics). Yes, it takes long, but, imo, accuracy and consistency is the bigger concern as mechanics seem to be getting longer and more complex as new prints come out, especially given that we’re supposed to reference the card for the mechanics rather than having to bring up the item-db constantly (I challenge anyone to fit the new gambling item descriptions on a card in a comprehensive manner; it’s basically impossible while keeping it legible).
A card printer with a nationwide database of “card print docs” would be able to ensure that every card is written with exactly the same description and mechanics while ensuring that it’s a legible font.
