  • 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.











  • Do you want to just block all sound or do you want the extra features that come with active noise cancellation headphones like speech passthrough? What you are proposing doesn’t exist because it makes no sense, active noise cancellation is done by recording the audio outside the headphone, inverting the amplitude and attempting to align the phase to cancel it out in real time.

    In reality active noise cancellation only works for more or less constant sounds below 1000Hz, anything higher than that and the headphones block exactly as much noise as any other pair of sealed headphones.

    You will get better noise reduction with IEMs than headphones, deep insertion headphones like Etymotic beat the pants off Bose for noise isolation at every frequency, are cheaper, and as a plus sound better than any noise cancelling set you can buy.
