If you're switching to an EV, you might be getting to know more and more ways of EV charging. Have you ever heard of an RFID card for EV charging? There are some EV chargers that need RFID cards to use. It is one of the latest innovations in charging technology. In this blog, we will explain what's an RFID card and how it works in EV charging. 

What is RFID?

RFID stands for radio frequency identification. It uses Radio-Frequency IDentification technology to stop and start EV charging sessions. It can come with a home EV charger as a smart feature but is more commonly used in managing public charging points or workplace EV chargers. RFID technology allows digital data encoded in an RFID card to be captured by a reader. Think of it like a key card that you use to gain entry at work or the gym. 

How does it work in EV charging?

RFID card is a popular method in public charging. These cards allow users who want to charge an EV by simply tapping the card against a dedicated card reader at the charging station. This generates a signal transmitted to the reader, which then communicates with the charging station's database to verify the user's identity and billing information. The charging station will begin the charging process if the information is correct.

Benefits of using an RFID card

Convenience, security, and cost savings, are the three main benefits of using an RFID card for EV charging. 

Accessing EV charge points using an RFID card cancels the need to juggle multiple access keys or apps; a single card suffices. Not only that, but you can also check real-time updates regarding your vehicle’s charging status. Compared to conventional payment methods, RFID card devices transmit encrypted data during transactions. RFID cards can also allow you to monitor how much you're spending on charging.
