An EV Driver is a person associated with an Organization. He/She uses the Chargestations within this organization for charging their EVs.

Tokens are security keys associate with an EV Driver. These are used to authenticate the driver for access to resources across the Organization such as Chargestations & Connectors.

Tokens may be of type "physical" e.g. RFID tags or "virtual" e.g. for drivers authenticating via Slack or other workplace directories.

Every charging event is recorded within eDRV as a transaction. Transactions include the token that was used to authorize and start the charging event along with various metrics that you may use to inform the driver.
