이 가이드의 대상은 다음과 같습니다. 충전 포인트 운영자(CPO) who want to accept on-site card payments on EV chargers with Nayax payment terminals, managed in Tridens EV Charge.
빠른 개요
Nayax VPOS works as a POS terminal that takes the driver’s card payment and talks to a POS back office to handle card owner verification and payments.
Nayax back office also communicates with Tridens EV Charge via OCPI (Open Charge Point Interface) protocol to exchange location, charger, tariffs, and session data and stay in sync. This enables the payment terminal to initiate charging sessions, keep track of them, and eventually terminate them, using the cost for payment.
What You Need Before You Start?
As the charge point operator, you need the following before you start:
- Active Tridens EV Charge environment with chargers onboarded.
- Establish an agreement with Nayax to open a new account for card payments, merchant payment processing, acquiring, and settlement.

How Nayax Terminal Works With Tridens EV Charge
Nayax’s role is the eMobility service provider, abbreviated as eMSP, having the back-office platform and payment terminals, which are also known as Points of Sale or POS.
Meanwhile, operators in the Tridens EV Charge platform have the role of charge point operator (CPO), controlling and monitoring charging locations and infrastructure.

Tridens EV Charge exposes your charging network via OCPI, so the Nayax platform with terminals can discover chargers, control sessions, and receive cost information.
Nayax reads payment cards on-site and communicates with its platform to authorize money resources based on the tariff configuration. Once authorized, Nayax requests the charging session to start on Tridens via OCPI. At session end, the final payment amount is captured from the payment card owner.

Configuring Nayax With Tridens EV Charge
Let’s go through the steps required to set up the Nayax payment terminals for EV charging in Tridens EV Charge.
1단계: OCPI 로밍 프로필 추가하기
Move to the Tridens EV Charge environment, open Roaming in the left menu, and create or reuse a Roaming Profile with CPO role for the OCPI protocol. Set a recognizable Name and Code of your business, Role, and your three-letter Roaming ID, which will represent you to Nayax.
Step 2: Add Nayax Roaming Platform
The next step in Tridens EV Charge is to go inside the Roaming Profile and add the Roaming Platform of Nayax.
Fill in Nayax platform’s recognizable Name with Code, select EMSP Type, Roaming ID, URL, and operating Country.
| 분야 | 권장값 |
|---|---|
| 이름 | Nayax |
| 유형 | EMSP |
| URL | https://nayax-energy-ocpi-prod.com/emsp/ocpi/versions |
| 로밍 ID | NAY |
| 국가 | Israel |
You can add or change Roaming Tariffs later for the cost calculations used for payments.
3단계: 등록 토큰 사용
In the next step of Roaming Platform configuration, a registration dialogue shows up. Insert the registration token (Token A) provided by Nayax and submit the form.
On the Roaming Platforms overview, select the recently created platform and hit Register Credentials action.
You can later update credentials to renegotiate or Invalidate credentials to stop the communication.
It is also possible to register credentials in the opposite direction, where the new token is generated by Tridens EV Charge at the platform configuration dialogue. If such a principle is used, you need to pass this token from Tridens EV Charge to Nayax support in a secure manner, after which Nayax will do the communication handshake. Use the URL that appears in the dialogue.
4단계: 충전 인프라 노출하기
You want to expose your charging infrastructure to Nayax. To achieve this, assign a unique Roaming ID for desired Areas, Chargers, and Connectors in Tridens EV Charge and enable roaming on chargers.
More details about applying the roaming settings on your charging infrastructure in Tridens EV Charge are described at 영역 그리고 로밍 프로필.

5단계: 비용 로밍 요금 할당하기
You need to define expense tariffs and prices for calculating the costs of using your chargers. These costs will be used for card payments by Nayax. Tariffs are schedule-based, with recurrence and one-time options. Expenses can be set for energy, charging time, parking time, and general flat fee, including VAT control.
Go to Roaming in the left side menu and select Tariffs, where you need to add a new regular type tariff definition with time validity.
In the next step, add the Tariff Elements with cost (energy, time, flat) and recurrence time settings.
할당 로밍 요금 on the charging infrastructure context (one of Site/Operator/Area/Charger/Connector) and also to the Roaming Platform of Nayax.
Step 6: Charger and Session Settings for Smooth Operations
As the CPO, you want to ensure that charging infrastructure events, including session events, are properly exchanged. Thus, the charger configuration in Tridens EV Charge must meet a few important considerations, resulting in events reported at regular intervals with sufficient data (power and energy progression) and covering border cases. This will contribute to payment terminals working properly and external users having a better charging experience.
몇 가지 일반적인 경험 법칙이 있습니다:
- Set a reasonable meter value reporting interval. We recommend 15 seconds.
- 최소한 전력 수입(kW) 및 에너지 수입(kWh) 측정값을 보고하도록 설정하세요.
- Align charger timeouts with Tridens’ ready-session expiration to avoid dangling sessions.
We advise you to follow the guidelines defined in 과금 세션 통합, and if facing an issue, it is likely you will find the solution for yours in the 충전 세션 오작동 페이지에서 일반적인 사례와 해결 방법 및 예방 조치를 설명합니다.
전체 흐름 테스트
Once your Nayax terminal is ready with Tridens and Nayax communication established, ensure locations with tariffs are exposed. Then you can proceed to the test flow and try out the charging sessions initiated from the terminal.
다음 작업을 테스트해 보실 것을 강력히 권장합니다:
- Approach the physical terminal of Nayax, plug in your EV, and tap the screen. You should be able to see available locations and chargers bound to this specific terminal and press the button to Start the charging session.
- Select your charger and present your payment card, which will be authorized (reserved) for the amount, as agreed with Nayax.
- If payment authorization succeeds, the charging of EV should start soon.
- Verify that the session is charging and that you can see the progress on Tridens EV Charge portal in the Sessions section.
- 결제 카드를 다시 제시하여 단말기에서 세션을 중지합니다.
- The payment terminal must show the receipt.
- Verify that amounts are properly calculated on the receipt and on Tridens EV Charge portal in Sessions based on your desired Roaming Tariffs configuration.
- Confirm that the amount is properly captured from the payment account, while the remaining reservation amount is released.
- We encourage you to thoroughly test the border cases:
- No charging expenses, for example if no energy is charged to EV. Expect the authorized payment amount to be released.
- Charging above the max. limit. The terminal is expected to automatically stop the session when the agreed max. amount threshold is achieved.
- Invalid authorization of payment card. Charging prevented.
- Request the stop of charging session from different sources: Tridens EV Charge portal, electric vehicle, terminal, charger’s emergency button. Confirm all scenarios end up in a properly completed session with payment capture.
- 키오스크 모드 또는 단일 충전기 모드. 사용 사례에 따라 다릅니다.
