Big Issue’s probably the exact sort of organisation that will be able to do it successfully - big infrastructure behind them and also each individual vendor operates as a de facto sole trader don’t they so makes sense for them to be made available to sellers and then they can individually choose whether to front up the extra for them.

Penoid tournaments have a stupid system where you find out who you’re playing by crowding round a printed list at the beginning of every round. It’s a faff.
At some tournaments they’re being replaced by a big QR code at the beginning of round one that takes you to an online list of pairings that gets updated each round. It is a huge improvement.
