They did it!
For years, up until last month, anyone wanting to connect to wifi in the Business Lounge in Paris had to request an SFR scratch card to reception, with a limited time 20-minute session.
That was hugely time consuming for everyone and often had problems of both quality of service and user experience (which network to connect to, where to put the numbers, who to ask for support, etc…).
The new process is trivial: walk into the lounge, the wifi password of the day is displayed on the reception desk. Sit down, connect, enter password, done.
A small step forward towards pervasive wifi, and we still have a few months to wait for wifi on the train.
