To be able to charge with RFID tag on our chargers you need to register as a customer with one of our partner service providers and order or register you RFID tag with them. We ourself only provide Drop-in charging to customers without registration, but we have opened up our network so that you can use multiple apps and RFID tags on our chargers. We are expanding our partner service provider list all the time, and you can see the currently active ones here. Please note that when you charge through a service provider they control the price and terms, and you have to agree to their terms.
