I'm from Canada. I traveled to Lisbon, then 2 days later flew to Barcelona. I was advised to get the QR Code, which I received almost instantaneously, about 70 hrs before my arrival Lisbon.
When I got to Barcelona, I searched highland low for the "blue sign"; eventually being guided buy an airport employee to a WRONG Immigration counter.
I asked several people, (including the Immigration officials) WHERE I needed to show this QR Code and where the "blue sign" was and they looked at me as though I had arrived feom another planet.
Apparently nobody had even head of the thing and I was guided out to the exit.
I am back in Lisbon today and start my Camino in a few days' time.
P.S. for those who care to know more.... here's the email I received with my QR Code......
