A trust box, for example. Or a simple donation option. The ticket (pay what you want) at my favorite punk gig in town. Etc.
In e.g. the Netherlands, the majority of payments go via a payment system iDeal¹. Its easy to start an ideal payment with a QR code. It's, by my knowledge, impossible to do so via NFC - other than via Apple Pay or Google Wallet.
Then, there are vast fleets of phones out there that don't even have NFC. I wouldn't be suprised if a majority of phones in use today don't have nfc chips on board.
And, a large section of the population won't switch on NFC even. For battery. For privacy, for fear etc. If not for scanning my glucose meter, I would've switched off NFC by default. I'm no tinfoil hat, but 30+ years of software development and hackery has kept me weary of such stuff.
