Does anyone seriously think QR codes will still be around in 10 years? They always struck me as clunky. They often don't work, require holding your phone in awkward positions for uncomfortably long periods of time and in many circumstances (e.g. a cashier wishing to expose a dynamically generated QR code to a customer) aren't practical. It's only because we haven't come up with cheap/reliable alternatives that all manufacturers agree to support that they're still in use.

Oh I understand now. It's the fault of the implementation of the QR reader that you use.

For example all UPI apps have near instant qr recognition at any angle. In fact on my phone, it takes longer for the camera to start than for the QR recognition to finish.

I also think there are a lot of things that QRs can do but NFC cannot. But the opposite is not true

Currently, yes. But in principle NFC or alternatives (that could be cheaply/ instantly generated anywhere, including by non-digital physical objects like pieces of paper) should be better and I'm willing to bet will be in the foreseeable future.

NFC is also used in south east Asia. Not just QR code.

Because at every pos in existence, I have the option of using my phone, my watch, or a card.

I am not exclusively tied to any of those devices (or their camera, which is a relative weakpoint in a smartphone).

I am also able to trust that the payment medium is so complex that there's a very low chance of phishing (i.e. pretty easy to print out a QR code to a malicious domain, hard to do that over ApplePay).
