"How many Amazonian trees are cut for yearly need of tickets in London?"
- harimau777 7y agoHonestly, probably zero. I'd be surprised if many corporations are making paper out of anything other than farm grown softwoods.
- danShumway 7y agoIf you're worried about the environment, recyclable paper stubs and small plastic/magnetic strips all seem pretty preferable to building, maintaining, and replacing hundreds or even thousands of high-precision sensors across a city. The power draw from a camera is probably always going to be higher than the power draw from a short-range NFC reader. And the NFC reader is also probably always going to be less delicate and last longer, which is good because the environmental downsides of throwing away paper are negligible compared to the downsides of sticking electronic components in a landfill.
- Polylactic_acid 7y agoIn most places you get a reusable NFC card.
- TeMPOraL 7y agoBetween ubiquitous Oyster cards and being able to pay-as-you-go with a regular contactless credit/debit card, I suppose it's close to zero.
- raxxorrax 7y agoHeh, and remember to think about all those children needing to fell those trees.
