RFID authentication is a technology available in CUPRA Chargers with internet access that allows enabling access to the charging point using a recharge card. You can activate and deactivate this function from the app. When this function is activated, charging is only possible with a previously enabled recharge card (RFID). The recharge card is the size of a credit card and serves as a "key". The charging process can only be initiated with a recharge card activated in the application. Internet connection is required during the card linking process.
