Agreed, you didn't say as much; you just implied it.
"What? The smartphone interface? On the contrary, you have to be close to the station for the price to be accepted thanks to their use of GPS to validate the price postings."
The gps really doesn't validate the prices, just the location, and I know you know that.
You might check the web site again; it does indeed do range checks on the prices. I'd
even go so far as to guess that they were there even before the mobile apps were completed.
