Problem deep dive
The wrong person gets charged
Plate-based payment does not charge a person. It charges whichever account a plate was once registered to, and trusts that nothing has changed since. In real life, things change constantly.
Why it happens
A number plate identifies a vehicle. The mapping from vehicle to payer is a static record, but who is actually driving varies trip by trip:
Shared and household vehicles
One car, several drivers, one registered account. Whoever drives, the same person pays.
Hire, lease and pool vehicles
The plate maps to a company, not to the driver of the moment. Recharging the right individual is manual admin.
Sold vehicles and stale registrations
A plate registered to a payment account keeps billing the previous owner until someone remembers to update it.
Permits and exemptions tied to people
Accessible permits, resident discounts and carer exemptions belong to a person, but plate-based systems apply them to a vehicle regardless of who is in it.
What it costs
Every mischarge produces a refund, a complaint or a dispute, and each of those costs staff time. The quieter cost is behavioural: a customer who has once been charged for someone else's journey stops trusting automatic payment, opts out, and goes back to slower, more expensive channels. Schemes and operators also carry the enforcement cost of permits and exemptions that cannot be verified against the person using them.
Who feels this
Parking
Auto-pay accounts bill the registered account holder for whoever borrowed the car, and accessible bays rely on permits that follow the vehicle rather than the person.
Clean Air Zones and road-user charging
Penalties go to registered keepers who may not have been driving, and person-linked exemptions cannot be checked against who is actually in the vehicle.
Fuel and EV charging
Pay-by-plate and plug-and-charge models bill an account whoever is at the pump or charger, which is a real exposure for fleets and shared vehicles.
Fleet and logistics
Fleet cards and depot accounts are routinely used by the wrong driver or the wrong vehicle, and reconciling who actually incurred a charge is ongoing admin.
How verified presence changes it
The patented method checks whether an authorised user's registered device is present at the location alongside the recognised vehicle before a charge is applied. In practical terms:
- The payment follows the person. The account charged is the account of someone verified as present, not whoever a plate was once registered to.
- Shared vehicles stop being a problem. Different drivers of the same vehicle can each be charged to their own account.
- Permits and exemptions can be verified. A person-linked permission applies when that person's device is present, not whenever the vehicle appears.
- Stale registrations lose their sting. Without a verified account holder present, a charge need not be raised automatically against an old mapping.
Implementation would be built by or with a partner into their own systems, and the design would depend on the use case. None of this exists as a Trust product today.
