Problem is that the current London model is somewhat more expensive, especially at the weekend.
I went from St Albans to St John's Wood on Sunday, changing to the tube at West Hampstead. Using the Tfl contactless system on a credit card registered with them, they charge for two singles at £8 each or £16 in total.
On Keygo I would have been charged a £9.20 return to West Hampstead on a Sunday, plus then using the Tfl system two tube fares of £1.60, or a total of £12.40.
The difference was even higher a couple of Sundays ago going to Stratford International and back, which doesn't include the tube, and so would all have been at a off peak return buying from a train company, but not via Tfl which I used.
