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.
