Re: Tesco
all of them scan the same way at the till - qr code.
It's an Aztec code.
If I was running a project to provide the same clubcard in multiple physical formats, I'd for sure be doing something so that I can see which format was being used rather than just the member id.
That just demonstrates that you're creepy too. I guess you're all in favour of exhaustive telemetry in all software as well. But again, why does that particular use case need a whole sixty 8-bit ASCII chars? A handful would do.
you can't use a loyalty card and then bitch about your usage being tracked.
I can bitch about them setting stupid prices for people without a loyalty card. Sadly I don't have a car, and Tesco is the only moderately-sized supermarket in plausible walking distance. As such, I'm doing all I can to keep the prices I pay sensible while avoiding their creepiness as far as possible.
I maintain that the amount of data stored in those Aztec codes is just weird.
