This guide assumes you have already added a charger to GridFlow Core. If you haven’t, please refer to the Adding Your First Charger guide first.
Overview
Adding your first RFID card involves two main steps:- Creating a Card Holder
- Creating an Access Profile and restriction limits
- Adding an RFID card to the Card Holder
Understanding Access Methods
Before adding an RFID card, it’s important to understand the two primary ways to use chargers in the GridFlow Core System.
Using RFID
This is the primary method for your team and internal members. You’ll manually set up RFID Cards for each user, making it unsuitable for public use.
Using GridFlow Drive
This method is designed for public usage. Users can access your chargers through the GridFlow Drive Web or Mobile App by scanning a QR code on the EV Charger.
Creating a Card Holder
It’s essential to create a Card Holder before adding individual RFID cards. A Card Holder represents the primary person who will be using the card and serves as the point of contact for anything related to this card.
