Not FinTech at first glance, but I thought the way they’re implementing it is interesting.
(n.b. I don’t subscribe to this nor am I affiliated with them in any way.)
For a monthly fee you get a card that lets you get one cinema ticket for free each day.
But they don’t have partnerships with the cinemas (yet?) and haven’t given the cinemas special equipment, it’s implemented currently with them giving you a standard bank card.
Presumably the card only does online transactions and will only authorise transactions from cinema chains and for the exact amount of one non-fancy/2D ticket in the relevant chain. Relatively clever way of doing it.
They say in their FAQ you can’t pre-purchase tickets, but if I did it at the box office rather than online, I’m not sure how they’d be able to tell. Nor if I worked out an exact combination of drinks/snacks that added up to the cost of one ticket, and on days I didn’t want to see a film, treated myself to some chocolatey snacks instead!
