If the passes could be linked up, you could simply offer a scheme, like the dartford tunnel uses, where it charges to an account and you have up to 24 hours to file a payment (online or by phone). If you don't pay up, your account and thus card becomes de-activated. That's if you can't pay on the spot for contactless or mobile tickets or have a valid pass.
