A practical solution for households, businesses, and other installations where one charging station is used by multiple users. The set includes 10 double NFC cards with keychains, a total of 20 different NFC IDs for convenient station unlocking and charging initiation. Each user can have their own NFC identification for easy access management. For monitoring consumption in kWh by individual users, an external OCPP service is required, as the Teltonika app only supports starting and stopping charging.
