RFID Card for electric cars: everything you need to know

Electric cars are transforming the mobility sector, making charging a key element for an efficient and smooth driving experience. Among the most practical solutions for accessing charging stations is the RFID card for electric cars.

What is the RFID card for electric cars?

The RFID card (Radio Frequency Identification) is a card that utilizes radio frequency identification technology to authorize vehicle charging at public and private charging stations.

It is a kind of contactless electronic key: just bring it close to the reader at the charging station to activate the process in a matter of seconds.

How does RFID technology work for EV charging?

The use of an RFID card for EV charging is based on a simple procedure, divided into three phases:

1. Approach: the user places the card near the reader of the charging station.

2. Authentication: the system verifies the data and authorizes the operation.

3. Activation of charging: if the identification is correct, the charging process begins.

This technology simplifies and speeds up access to charging stations, eliminating the need to enter codes or use apps.

Advantages of the RFID card for electric cars

The adoption of an RFID card for charging electric vehicles offers numerous benefits:

• Convenience: charging the car becomes quick and intuitive, without having to manage applications or codes.

• Security: user data and transactions are protected by advanced encryption systems.

• Traceability: it is possible to monitor consumption and charging, facilitating the management of energy expenses.

• Reliability: it works even without an Internet connection, ensuring continuous service.

An additional advantage is the ability to use a single card for multiple charging networks, avoiding the need to manage multiple access keys.

How to obtain an RFID card for EV charging?

The RFID card can be requested through various channels:

• Electric mobility platforms

• Automakers

• Charging apps and services

After the request, the card is sent to your home and must be activated before use.

General procedure to obtain an RFID card:

• Registration: create an account on the website or app of the chosen charging service provider.

• Request for the card: go to the section dedicated to RFID cards and follow the instructions to request one.

• Shipping and activation: after the request, the card will be shipped to your address. Once received, you will need to activate it by associating it with your account via the app or the service provider's website.

How to use the RFID card to charge the car?

1. Find a compatible charging station: check that the station supports the use of RFID cards.

2. Bring the card close to the reader: position it in the dedicated area of the station.

3. Wait for confirmation: a light or sound signal will indicate successful authentication.

4. Connect the charging cable: plug the cable into the vehicle socket to start charging.

5. End the session: disconnect the cable and, if requested, use the card again to complete the operation.

Security and data protection with the RFID card

RFID cards use encryption protocols to protect transactions. However, to enhance security, it is advisable to:

• Use a shielded case: reduces the risk of unauthorized readings.

• Do not share access data: keep the card and account credentials confidential.

• Regularly check transactions: periodically review the charging history to identify any anomalies.

Costs and subscriptions for RFID EV cards

Costs vary based on the provider and the plan chosen:

• Free cards: some providers offer RFID cards at no initial cost, allowing you to pay only for the energy actually used during charging.

• Cards with monthly subscription: other operators offer monthly subscriptions that include a certain number of kWh at a fixed price, often with reduced rates compared to pay-per-use.

Alternatives to the RFID card for charging electric cars

Although RFID cards are one of the most commonly used solutions, there are equally valid alternatives:

• Mobile apps: many providers have applications that allow you to start and monitor charging directly from your smartphone.

• Contactless payment systems: some charging stations accept payments via credit/debit cards or smartphones enabled for contactless payment, offering greater flexibility. 

• QR codes: some stations allow charging to be initiated by scanning a QR code, facilitating access without the need for physical cards.

These alternatives offer greater flexibility, reducing the need to carry a physical card.

Compatibility of the RFID card with different charging networks

RFID cards can be compatible with different charging networks or limited to specific operators. Before choosing a card, it is important to verify:

• Check geographic coverage: make sure that the supported network covers the areas where you plan to use the vehicle.

• Check compatibility: verify that the card is accepted by the charging stations you use most frequently.

• Consider international use: if you plan to travel abroad, check the possibility of using the card in other countries.

FAQ – Frequently Asked Questions

Do you need an RFID card to charge an electric car?
No, it is not strictly necessary. Many providers offer mobile apps that allow you to start and monitor charging directly from your smartphone. However, an RFID card can make the process quicker and easier, especially in situations where using a smartphone might be inconvenient. 

Are RFID cards compatible with all charging stations?
Compatibility depends on the card provider and the charging network. Some cards only work with certain networks, while others offer interoperability with multiple operators. It is important to check with your provider about the coverage and active partnerships. 

Can I have multiple RFID cards for one car?
Yes, it is possible to own and use multiple RFID cards linked to different providers or charging services for the same vehicle. This can be useful for accessing a wider range of charging stations or taking advantage of different rates and promotions.

What to do if the RFID card does not work?
If the RFID card malfunctions:

• Check your balance or activation: make sure the card is active and any credits or subscriptions are valid.

• Repeat the operation: try to bring the card back close to the reader, ensuring you position it correctly.

• Contact customer service: if the problem persists, contact your provider's support for assistance.
