The route a fine takes
A camera or warden records the registration. The authority contacts the registered keeper, which is the rental company. The company either pays and recharges you, or supplies your details so the authority bills you directly.
Either way, an administration fee is normally added for handling it. That fee is charged per fine, so several small violations become disproportionately expensive.
Why the card stays on file
The deposit may be released before fines arrive, but the card details remain on the agreement and the contract permits later charges. This is the mechanism by which a charge appears a month after you got home.
It is also why the agreement and any receipts are worth keeping well past the end of the rental.

Disputing a charge
Ask for the evidence
Request the original notice showing the date, time, location and registration. A charge without an underlying notice should not stand.
Check the timing
Confirm the violation falls inside your rental period. Fines from before collection or after return are not yours.
Produce your own record
A parking receipt or toll payment showing you did pay is the strongest response.
Reducing the risk
- Keep every parking ticket and toll receipt until the deposit clears.
- Photograph signage where the rules are unclear.
- Confirm at handover how tolls are billed on the car.
- Note the mileage and time at both collection and return.
