  • The article more or less covers it. Asian countries without a credit card culture mostly transitioned to QR because it was easy with minimal equipment changes required. Those with widespread credit cards accept tap and QR (e.g. Taiwan widely accepts QR payments, Google pay, Apple pay, credit cards, and transit cards).

    Since the western world has been on credit cards for decades that is the solution that is accepted there with QR payments being almost exclusively in businesses that have a customer base from Asian countries. Even then the US is odd compared to other countries since they never really adopted chip and pin.











  • Exactly, there is so much industrial waste before a product makes it to you. Yet everyone focuses on the consumer use which makes it inconvenient for the end user and ignores all the “invisible” waste which would require investment from businesses to fix but would have a far larger effect on the environment. Not being able to get a plastic straw or PE film bag doesn’t really improve anything since the alternatives are worse and in many cases far worse for the environment even when reused.






  • Yes, also Lithium Manganese Spinel cells have been around since 1996 and also don’t contain any nickel and cobalt. This is good but many vehicles and devices still use NMC and NCA due to the better specific energy density which is where LFP is limited (but can output more power and is much safer). Tesla (and every EV manufacturer) compromises on the battery depending on what chemistry they use, where if they could reduce the need for expensive metals while maintaining specific energy it would be pretty newsworthy.
