There was a donation box at the door: really easy. I'm not about to go hunting around the church for a contactless connection hidden somewhere - it's a house of worship, not the Krypton FactorYou probably didn’t look hard enough
It's also the case that contactless may not be enough. I've just this minute come back from my local store and I couldn't use contactless payment, I had to put in my PIN. So, we're really talking about card readers.
