Charging access and payment methods depend on the specific charging network the station belongs to. Some require monthly memberships, RFID cards, or key fobs. Here is a helpful link to a guide about the major charging networks with their contact information provided:

We have a convenient in app payment method, Pay with PlugShare, that allows you to simply pay for a charging session with your credit card. Pay with PlugShare is available at SemaConnect stations, Webasto (formerly AeroVironment) stations along the West Coast Electric Highway in OR and WA, and select GE WattStation locations. We have plans to expand Pay with PlugShare to additional networks in the future. Here is a link with more information: Pay with PlugShare FAQ Home Page

PlugShare is the most popular charging station locator with the largest database of charging stations and we cover all the different networks, non-networked stations, and PlugShare members who have decided to share their residential charger for use in a pinch. You do not need a membership or payment card to access PlugShare. Here is a link to our general FAQ for more information: PlugShare FAQs
