Parking payment via WhatsApp: how ANPR and Mollie replace the pay station

What consistently goes wrong with pay stations

A pay station is expensive to buy, more expensive to maintain, and a reliable target for vandalism on any unattended site. But beyond the cost, there is a more fundamental problem: the machine stands between the driver and the exit.

Most drivers want to leave quickly. They have a meeting, a flight, or simply no patience for a machine that wants a ticket number, then a PIN, then a receipt, then the walk back across the car park to the barrier. Sites with pay stations consistently see more turnaways at the entry: drivers who decide to park elsewhere because they do not want the friction.

For operators of a commercial car park — whether or not they serve a retailer, hotel, or venue — that friction is measurable revenue loss. The question is not whether you want an alternative, but what that alternative looks like.

The approach: licence plate recognition at entry, payment link at exit

The cashless alternative works as follows. At the entrance, an ANPR camera reads the licence plate and logs the arrival time. The barrier opens. The driver parks without doing anything.

At departure — either when the vehicle approaches the exit barrier, or a fixed number of minutes beforehand — the system sends a WhatsApp message to the phone number linked to that plate. The message shows the parking duration, the amount due, and a payment link. The driver pays via iDEAL, credit card, or another Mollie-supported method, and the barrier opens as soon as payment clears. Done.

First-time visitors who have not yet linked their number complete a one-time registration step at entry — entering their plate via a QR code at the entrance, or through WhatsApp. That is a single step, done once. After that the system recognises the plate automatically and goes straight to the payment step on every subsequent visit.

Mollie as the payment layer

Mollie is the payment processor driving the system. It supports iDEAL, Visa, Mastercard, Apple Pay, and a range of other methods — covering the full range of what Dutch and international visitors actually use. Drivers do not need to install an app or create an account: the payment link works in any browser.

Each transaction is processed per session, automatically linked to the plate and the duration. The operator sees all transactions in a dashboard, including failed payments and outstanding amounts. Sites that work with regular clients — such as an office that reimburses visitor parking — can route those bookings to a monthly invoice rather than an individual payment per visit.

Mollie charges transaction fees rather than a fixed licence fee. That makes the model particularly attractive for operators with variable occupancy: payment costs scale with actual usage.

What the driver experiences

The driver sees a barrier open at entry. No actions required, no ticket to collect, no machine to find. When they leave, a WhatsApp message arrives with the amount and a payment link. One tap via iDEAL, and the exit barrier opens.

For returning visitors, the second visit is fully automatic: the system recognises the plate, calculates the time, sends the link. The only active step is approving the payment — ten seconds, at most.

The only friction point is the first visit, when the plate has not yet been linked to a phone number. That registration is a one-time step via WhatsApp or the QR code at the entrance. Most drivers are willing to do it once if the rest of the parking experience is frictionless from that point forward.

When a pay station still makes sense

There are situations where a pay station or kiosk remains a useful fallback. Tourist destinations with high volumes of international visitors — drivers without a Dutch number or without WhatsApp — need an alternative path. The same applies to older visitors or anyone who simply does not want to use WhatsApp for payment.

A hybrid setup is straightforward: an ANPR camera handling all licence plate registration, complemented by one compact exit kiosk for drivers who skip the WhatsApp flow. That is a substantially simpler system than two or three full pay stations — and it preserves the automated flow for the majority of visitors.

Which sites benefit most

The model works best at sites where visitors expect a modern, smooth experience — and where the operator has a clear interest in minimal staffing. In practice, that means:

• Commercial car parks serving retail, hospitality, or office buildings
• Hotels charging for parking without a front-desk agent handling each transaction
• Event venues receiving hundreds of visitors at once and wanting an automated payment flow when they leave
• Hospitals and clinics that want to decouple visitor payment from the front desk

At all of these locations, the combination of ANPR and a digital payment link outperforms a pay station — not only operationally, but in payment completion rates too, because drivers do not have to remember to visit a machine before they leave.
