This is an interesting move. They’re starting off by selling a subscription for zones 1 + 2 in London, though at a cheaper rate than a weekly pass. Interestingly the card has a MasterCard logo on it, so I assume that it will act as a contactless card rather than an oyster card.
I don’t think this initial offering has much going for it (other than an unsustainably low price), but if they can actually make a card that works with multiple transit smart card systems worldwide, that would be pretty cool.
I’d love to give it a try, as I’m a big fan of Citymapper as a company, but I walk to work most days, so it’s not going to be any good for me personally.
