RFID Card
Additional RFID card for EV MR WATT charging stations and wallboxes. Allows starting and stopping the charging session in contactless mode, without the need for a smartphone or app. Ideal for managing multiple users or vehicles on a single charging infrastructure.
The RFID Card for EV charging station is the essential accessory for managing access to MR WATT wallboxes and charging stations in a simple, fast, and secure way. Thanks to RFID (Radio Frequency Identification) technology, simply hold the card near the station reader to start or stop the charging session, without needing a smartphone or a dedicated app.
Why choose an RFID Card for EV charging?
In environments with multiple electric vehicles—such as company fleets, condominiums, shared parking areas, or workshops—RFID card management is the most practical and reliable solution. Each card is paired with a single user or vehicle, allowing the system manager to track consumption per individual card, restrict unauthorized access, and simplify reporting of charging sessions.

Frequently asked questions
Is the MR WATT RFID Card compatible with any wallbox?
The RFID card is designed to work with MR WATT charging stations and wallboxes equipped with an integrated RFID reader. Before purchasing, check that your wallbox model supports authentication via RFID card.
Can I assign an RFID card to each user of the system?
Yes. By purchasing multiple RFID cards, you can assign one to each authorized user or vehicle. This allows you to track consumption per individual card and manage access separately for each family member or each vehicle in the company fleet.
Is an app required to use the RFID Card?
No. The RFID Card allows you to start and stop charging completely independently, without needing to use a smartphone or an app. Simply hold the card near the station reader.
How many RFID cards can I associate with the same wallbox?
The maximum number of cards that can be associated depends on the specific wallbox model. Consult your device manual or contact MR WATT support to find out the limit for your system.
Does the RFID Card also work outdoors, in rainy or cold conditions?
RFID technology is robust and reliable even in adverse weather conditions. The card does not require its own power supply or a connection, so it works correctly even in rain, cold, or humidity, provided the charging station is correctly installed outdoors.
