The RFID card for electric vehicle (EV) charging is one of the latest innovations in charging technology. This guide will explain RFID cards, the types of RFID cards available, and how to use them for EV charging.

What is an RFID Card for EV charging?

Radio Frequency Identification (RFID) technology has revolutionised how we interact with many aspects of our daily lives – from contactless payments to automated library systems.

An RFID card for EV charging allows you to access, authenticate yourself and pay at electric vehicle charging stations.

The best part? These cards or key fobs communicate wirelessly with chargers through radio waves – no internet connection is required! An RFID card is essential under any circumstances. Suppose you’re using an everyday personal charging station or encountering public charging points during a long road trip. By simply tapping the RFID card at selected public chargers, drivers can quickly initiate their charge session without any fuss— it’s truly that simple.

It’s so user-friendly that you might wonder why there isn’t an equivalent ‘contactless payment’ solution for traditional gas pumps yet.

Types of RFID cards for EV charging:

As the demand for electric vehicle (EV) charging stations rises, different types of RFID cards have been introduced to cater to diverse user needs. Each type of RFID card has its own features and benefits, enabling smoother and more efficient use of EV charging infrastructure.

Let’s look at three different types of RFID cards available, including personal access apps and cards, fleet cards, workplace cards, and universal access cards and apps.

Personal access apps and cards

Personal access apps and cards allow private electric vehicle owners to access various public or semi-public charge points readily.

To do so, most personal access apps and cards require users to create a secure account linked to a specific card or application on their smartphone. By using your personal RFID card for EV charging or activating the app’s scan feature at a compatible station, you can kick-start the charging process instantly – anytime you need it. It’s convenient, adaptable, and tailored to individual driving patterns. Moreover, these cards often track your power usage statistics over time, which helps you monitor energy consumption effectively.

Fleet cards

For corporations administering fleets of electric vehicles, fleet RFID cards present themselves as a prime solution. Remarkably functional in design, fleet cards centralise all payment transactions from multiple drivers under one account – offering easier expenditure tracking for businesses.

Workplace cards

Geared towards businesses transitioning to electric company cars or encouraging employees’ shift towards electric vehicles – workplace RFID cards offer streamlined EV charging solutions right at the office premises.

Workplace cards are able to manage sharing behaviour at shared charge points more fairly; employers use them to assign charge times based on employee needs without any heavy lifting involved intuitively.

In addition to simplifying scheduling regimes within workplace settings, these RFID cards can distinguish between employee usage (often offered free) versus guest use, which may carry a fee.

Benefits of using an RFID card for EV charging

The main three benefits of using an RFID card for EV charging include convenience, security and cost savings. Let’s take a closer look at this.


Autonomy and adaptability take centre stage when we discuss the convenience of using an RFID charging card. Electric Vehicle (EV) owners can enjoy seamless charging experiences at different stations without worrying about incompatible systems or unique requirements from each service provider.

Accessing EV charge points using an RFID card eliminates the need to juggle multiple access keys or apps; a single card suffices. You can also check real-time updates regarding your vehicle’s charging status.


In today’s digital age, security remains a predominant concern—especially concerning financial transactions. RFID cards for EV charging shine through with their robustness against fraudulent activities.

Compared to conventional payment methods, these nifty devices transmit encrypted data during transactions. The result? A secure environment that leaves limited room for unauthorised exploitation.

Cost Savings

Implementing an RFID card implies signing up for potentially significant cost savings. Shifting from traditional fuel-guzzling vehicles towards more sustainable options is already associated with its monetary advantages, like reduced fuel costs.

How to use an RFID card for EV charging

Operating an RFID card for EV charging is a relatively straightforward process. Your journey towards using RFID cards begins with the following.

Step 1: Locate a charge point

Locate an EV charging point that accepts RFID cards by looking online or using your RFID app. By selecting your location, these tools will illustrate all available EV charging stations near you. They can also provide information such as the speed of the charger, availability status, and costs associated with each station, helping you make the best choice based on your needs.

Step 2: Plug in your vehicle

After reaching the chosen charge point, it is vital to park your electric vehicle (EV) in close proximity. Subsequently, connect your EV to the charger.

Step 3: Tap the RFID Reader with your card

You’ll find that, more often than not, every charge point has a reader where you’re supposed to tap your RFID card before plugging in your car. This action authenticates and initiates power flow from the charge point to your EV battery system – it’s similar to swiping a credit card before any transaction can be authorised.

Step 4: End the charge

Once your battery reaches maximum levels or is sufficient for your travel needs, either manually stop it via the app or disconnect the charger from the Electric Vehicle’s interface, simultaneously tapping off the session by tapping your RFID card into the charger.


Let’s address some common questions about the RFID card for the EV charging process.

Is it safe to sit in my EV While it is charging?

Yes, indeed. Sitting in your electric vehicle (EV) while charging it with an RFID charging card doesn’t pose any health or safety risk. 

Nonetheless, different manufacturers may impose specific advice or guidelines regarding occupying the vehicle while it is connected to a charge point. Therefore, it is advised that you check your user handbook for any unique directives related to your particular electric vehicle model.

How Does an RFID Card Work Without Power?

The ingenuity of Radio Frequency Identification (RFID) lies in its ability to operate without needing its power source. The RFID card employs passive technology, activated by radio waves emitted from the reader. More specifically, when you bring your RFID card closer to a compatible reader (such as one affixed to an EV charging station), the reader emits low-power radio waves that energise a small electrical circuit within the card, allowing instantaneous identification and connection between both devices.

Understanding this underlying principle — that data stored on an RFID chip can be read without a constant power supply.

What Size is an RFID Card?

Generally, standard RFID cards may vary slightly in dimensions; however, most comply with ISO standards measuring 85.60 mm * 53.98 mm—the size of a typical credit card—making them portable and convenient. Some come in smaller sizes, too, such as key fobs or wristbands, offering users flexibility based on their preferences or needs.


The article discusses Radio Frequency Identification (RFID) technology and how it’s used for electric vehicle charging. It explains what RFID cards are, the types of RFID cards available, and their benefits. The four types of RFID cards covered are personal access apps and cards, fleet cards, workplace cards, and universal access cards and apps. The article highlights the convenience, security, and cost savings that come with using an RFID card for EV charging. In conclusion, RFID cards are an essential tool for electric vehicle owners, providing a secure, easy-to-use, and cost-effective way to access and pay for EV charging.
