Even so, I would assume the amount of children travelling solo must be very low. You can open a bank account and get a debit card at about 12-13 these days.
Anyone younger than that will likely have a prepaid school bus ticket, or be travelling with a parent/guardian who will pay with his/her contactless card.
Replied on the other thread as it's more generic than the legalities of Stagecoach's scheme.
