Payment Terminal Overview

Lynkwell’s Network Manager platform supports many industry-leading EV charging payment terminals. Sites using Lynkwell have seen that up to 70% of sessions are started using payment terminals when activated, making them an attractive feature for a growing charging network. This is especially true for satisfying EV drivers who are just traveling through, want to save time, and do not wish to download an app to charge.

1. Merchant Account Setup

   Lynkwell recommends configuring your merchant account before your charging stations are installed, as it normally takes multiple business days to complete the setup, depending on which vendor you are working with.

   Note: To complete the signup form, you must have signatory power at your organization and the organization's business information, such as the Employer Identification Number (EIN).

   Payter Merchant Account Setup

   To create a merchant account, visit the Payter Merchant Account Signup page. The person filling this out will need signing permissions for the company to be able to complete the form. It will take a few business days for the payment provider to process and complete the request. Once this is completed, Payter will provide you with a Merchant Account Number, which is required to activate your payment terminal.

   If you are subscribed to Lynkwell's remote support offering, our team will complete the remaining steps in this guide.

   Nayax Merchant Account Setup

   Nayax terminals do not require a separate merchant account. Your merchant account is set up and managed directly through the Nayax platform. During onboarding, Lynkwell links this account to your network on your behalf. For any questions, please contact Lynkwell support.

2. Self-Service Terminal Activation

   Some payment providers require you to register or activate the payment terminal with their system before adding it to the Lynkwell Network Manager portal.

   Payter Payment Terminal Activation

   Before activating a Payter payment terminal inside the Lynkwell platform, you will need to register the device using the Payter Terminal Activation form. You will need the Merchant Account Number provided in the previous step to do this. You will also need general contact information, the charging station ID to which the payment terminal is attached, and to specify whether or not the terminal is connected via a LAN cable.

   Nayax Payment Terminal Activation

   Nayax terminals do not require manual activation. When you add a Nayax terminal to a charging station in Network Manager (Step 3), the system automatically registers and activates the terminal with Nayax. You can monitor the activation status directly in the Payment Terminal section. The initial Pending status will change to Active once activation is complete or update to Failed if an issue occurs.

3. Assign Terminal to Charging Station

   Once you have set up your merchant account and activated the terminal, the final step is adding it to the charging station in the Network Manager portal. If you go through Lynkwell support, then this will be taken care of by our team. The integration type you select depends on your payment terminal provider: Hardware or Cloud for Payter terminals, and Terminal for Nayax terminals.

   Option 1: Hardware Setup (Default)

   To assign the payment terminal to a charging station in the Network Manager portal, you will want to follow these steps below:

   1. Locate the charging station in Network Manager either from the global search, locations page, or stations page.
   2. Select the charging station and scroll down to the Payment Terminal section.
   3. Click on Add new on the right side of this section.

      

   4. Enter the serial number of the payment terminal installed on the station.

      

   5. Select the Provider of the payment terminal from the drop down list.

      

   6. Enter the Pre-Authorize amount for the payment terminal.

      This is a hold amount that it puts on the card since we don't know the total cost of the session until after charging is complete. This is similar to holds placed on credit cards at gas station pumps.

      
      

      Note: The input field is in cents, but will convert and display the amount in dollars after saving the changes. (i.e. If you want a hold of $25, you would enter 2500 as the input value)

      
      

      

   7. Select the Integration Type, in this case Hardware.

      

   Option 2: Cloud Activation (Advanced)

   To assign the payment terminal to a charging system on Lynkwell's backend, you will want to follow these steps below:

   1. Locate the charging station in Network Manager either from the global search, locations page, or stations page.
   2. Select the charging station and scroll down to the Payment Terminal section.
   3. Click on Add new on the right side of this section.

      

   4. Enter the serial number of the payment terminal installed on the station.

      

   5. Select the Provider of the payment terminal from the drop down list.

      

   6. Enter the Pre-Authorize amount for the payment terminal.

      This is a hold amount that it puts on the card since we don't know the total cost of the session until after charging is complete. This is similar to holds placed on credit cards at gas station pumps.

      
      

      Note: The input field is in cents, but will convert and display the amount in dollars after saving the changes. (i.e. If you want a hold of $25, you would enter 2500 as the input value)

      
      

      

   7. Select the Integration Type, in this case Cloud.

      

   Option 3: Terminal (Nayax)

   To assign a Nayax payment terminal to a charging station in the Network Manager portal, follow the steps below. When added, the terminal will automatically begin the activation process with Nayax.

   1. Locate the charging station in Network Manager either from the global search, locations page, or stations page.
   2. Select the charging station and scroll down to the Payment Terminal section.
   3. Click on the Add new button.
   4. Enter the serial number of the payment terminal installed on the station.
   5. Select Nayax as the Provider of the payment terminal from the drop down list.
   6. Enter the Pre-Authorize amount for the payment terminal.

      This is a hold amount to authorize the driver's card. Once the charging session is complete, the payment method will only be billed the final session amount.

 This isn’t a fee and is typically updated within 5-10 business days.

      
      

      Note: The input field is in cents, but will convert and display the amount in dollars after saving the changes. (i.e. If you want to set a hold amount of $25, enter 2500 as the input value)

   7. The Integration Type will be automatically set to Terminal for Nayax providers.
   8. Save the changes and monitor the activation status.

      The status will display as Pending during activation, then change to Active once complete, or update to Failed if an issue occurs.

      
      

      Most terminals are activated within 2-3 business days. If your status still shows "Pending" after this time, reach out to Lynkwell Support for help.

   Note that the Cloud option is an advanced integration for Payter terminals only. If you aren't sure which option to use, please reach out to Lynkwell and we will help you determine the right setup for your terminals.

4. Station Configuration

   Once you have added the payment terminal to the station, confirm that the station is configured properly to use it. Consult your station's owner manual for this step. There should be, at a minimum, a configuration key for the pre-authorize amount, authentication, and the charging amount (per kWh or per minute).

   Example: You are required to configure a Tritium unit to display the pricing for charging. In the example below, the rate applied to the station is using energy $/kWh instead of time, and that it is for $0.55/kWh. Set this configuration in Network Manager (Stations > EVSE Commands > Advanced Commands > Change Configuration) using the Configuration Name (key): CreditCardPricePerKwh and your desired Configuration Value and pressing the Send button.

   You can confirm the update by selecting Advanced Commands > Get Configuration (Using Keys) and using CreditCardPricePerKwh as the key and pressing the Send button. Navigate to Real-Time Logs, to see the following in the return data:

   {
      "configurationKey": [
         {
            "key": "CreditCardPricePerKwh",
            "readonly": false,
            "value": "55"
         }
      ]
   }

5. Verify

   After making the above changes to the charging station(s), verify that they are working as intended. The best way to do this is to have a vehicle on standby to attempt a charging session using the payment terminal. Make sure that you can start the charge and that once it is done, the payment is processed accordingly. If you use Payter, you should be able to see on their backend the amount of that session. You can use it to reconcile with your records. For Nayax terminals, verify that the terminal activation status is not in a Pending state in Network Manager, and confirm with Lynkwell support that the locationId and evseUid have been configured in the Nayax system before testing.
