QR Codes in Electric Vehicle Charging: The Digital Shortcut to Convenience and Safety

Have you ever found yourself standing in front of a charging station—maybe in a city you’re not familiar with—and had that moment of hesitation: “Now, how do I start it?” That’s exactly when the QR code becomes your best friend.

What at first glance appears to be just a small square of pixels is, in reality, one of the most effective tools for making electric mobility truly accessible. It’s not just about technology: it’s about ease of use—the ability to charge without having to download an app, create an account, or follow complicated steps.

How does QR code top-up work?

Using the QR code is quick and easy and takes less than a minute. The process consists of four sequential steps:

1. Point and scan: Open your smartphone’s camera and aim it at the code printed on the charging station, which is usually located near the outlet you plan to use.
2. Open the link: a pop-up notification will appear on the screen. Tap it to be redirected to the carrier’s top-up webpage—no registration or login required.
3. Select your payment method and connect the cable: choose your preferred payment method and plug the charging cable into your car and the charging station, following the brief on-screen instructions.
4. Start and monitor: Confirm the operation on your phone to begin power delivery. You can track the session’s progress directly from your smartphone’s browser and stop it with a single click when you’re done.

Why the QR code is the real digital “shortcut”

In the world of public charging, the QR code serves as an immediate link between the physical world—the charging station—and the digital world—the payment process. That is why it has become a fundamental standard in the modern charging experience.

Powy, for example, supports this technology at its charging stations, combining it with other charging methods to offer maximum flexibility to every driver.

• Universal access: this is the ideal solution for occasional users. Even without registering with a specific provider, the QR code allows you to access a direct payment page—often via credit card or digital wallets like Apple Pay and Google Pay—in just a few steps.

• Reducing human error: Manually entering the charging station’s identification code can lead to mistakes. Scanning, on the other hand, allows the charging point to be identified uniquely and immediately, minimizing friction.

• Instant transparency: even before plugging in the cable, the QR code clearly displays prices per kWh, available power, and current promotions, giving you a full understanding of the session.

For operators, the goal remains the same: to eliminate all friction and make charging a natural, quick, and intuitive process.

The Threat of Phishing: How to Protect Yourself Effectively

As electric vehicle adoption grows, charging infrastructure has also become a potential target for digital fraud. There is increasing talk of “QRishing,” a phenomenon that combines QR codes and phishing.

The scheme is simple but insidious: a counterfeit QR code is placed over the original one and redirects users to a clone site, with the aim of stealing payment information.

That is why it is essential to pay attention to certain key signs:

• Visual and tactile inspection: On most charging stations, QR codes are integrated into the design or protected by durable materials. If you notice overlapping stickers, raised edges, or misaligned elements, it’s best not to scan the code.

• Check the website: After scanning, always make sure the address begins with “https://” and that the domain clearly belongs to the official operator.

• Be wary of urgent messages: requests for immediate action or fake timers (“enter your information within 60 seconds”) are often a common sign of phishing.

Security measures should never create pressure: this is one of the most reliable signs of a fraudulent attempt.

Beyond QR codes: what other ways are there to top up?

Although QR codes are a universal and widely used solution, the charging ecosystem offers various options designed to accommodate different usage patterns.

• POS terminal: increasingly common, especially at Fast and Ultrafast charging stations. It allows for contactless payment via card or smartphone, without the need for scanning or registration.

• Charging apps: designed for frequent chargers. Dedicated apps (such as the Powy app), whether used on the provider’s own network or via roaming, allow you to save payment methods, access special rates or subscriptions, and monitor the progress of your charging session in real time.

• RFID device: a well-established technology that is still widely used. Simply hold your card or device near the reader to start charging. This is particularly useful if you have an unstable connection or a dead smartphone battery.

• Plug & Charge: This represents the cutting edge of the “worry-free” experience. Although not yet widely available, it allows the car to communicate directly with the charging station via encrypted protocols, automatically initiating the charging process without the need for apps, cards, or QR codes.

A tip for stress-free travel

QR codes remain an effective tool, especially when used wisely. Taking a few seconds to examine the code before scanning it is a good habit that enhances security and reduces the likelihood of unexpected issues.

If you notice any visual abnormalities, damaged QR codes, overlapping stickers, or signs of possible tampering, you should always stop the operation and report the issue to the operator to allow for a prompt investigation and help ensure the security of the infrastructure.

A simple step that makes the charging experience smoother, more reliable, and stress-free.

FAQ: Frequently Asked Questions About Topping Up via QR Code

What happens if the QR code is damaged or unreadable?

If the QR code does not work, you can start the charging session using the other standard methods, such as the app, a POS terminal, or an RFID device. Alternatively, you can almost always start the session using the charging station’s unique identification code via a dedicated web page. If you encounter further difficulties, we recommend contacting the operator’s customer support, which is available to assist you in starting the charging session.

Is paying via QR code more expensive?

Each provider sets its own pricing policies, but generally there is no specific surcharge for using the QR code. Rates are always transparent and are clearly displayed before the top-up begins, ensuring full awareness of the service cost.
