NFC Keychain for EV Charging

NFCKEY is a wearable NFC keychain that replaces plastic EV charging cards and RFID key fobs at public charging networks, workplace chargers, and fleet charging facilities. NFCKEY is issued and managed by the operator — working with existing chargers, OCPP-compatible backends, and charging management systems.

What NFCKEY Replaces in EV Charging Systems

What NFCKEY replaces

✓

NFC EV charging cards

✓

Plastic RFID key fobs used for charger authentication

✓

Physical charging credentials issued to drivers or fleet users

NFCKEY acts as an NFC keychain that is presented to a charger reader to identify the driver, vehicle or associated account.

What NFCKEY does not replace

✕

EV chargers or charge points

✕

Charging management software or backend platforms

✕

Billing systems, tariffs, payment processing or energy management logic

NFCKEY does not start, meter, or bill charging sessions on its own. All authorization, session control, and billing decisions remain fully managed by the EV charging management system.

Common Uses

How NFCKEY Is Commonly Used in EV Charging

In EV charging environments, NFCKEY is commonly used for: 

  • Driver or vehicle authentication at charging stations 
  • Fleet charging access for company vehicles
  • Residential and workplace charging where access is restricted to authorised tenants, residents, or employees
  • Subscription-based charging programs linked to user or vehicle accounts 
  • Roaming credentials used across multiple charging networks or operators within an interoperability scheme

The wearable format reduces lost or forgotten charging cards while preserving the same tap-to-charge authentication flow already used by existing RFID charging credentials.

Why NFCKEY

Benefits of Using NFCKEY in EV Charging

When deployed in an EV charging system, NFCKEY delivers practical benefits as a wearable NFC keychain and RFID credential for charging operators and drivers alike

Always-With-You Form

Always-With-You Form

NFC keychain stays attached to car keys, bags, and lanyards — reducing lost or forgotten EV charging cards at public and workplace charging points

Reinforced Sleeve Mount

Reinforced Sleeve Mount

High-strength sleeve eyelet rated up to 40 kg tensile load — preventing eyelet wear and tear under outdoor charging conditions

System-Native Charging Behavior

System-Native Charging Behavior

NFC keychain operates with system-native authentication behaviour — preserving existing OCPP-compatible charging authorisation and billing logic

Customisable Design

Customisable Design

NFC keychains with full design customisation options — enabling operators to identify fleets, user groups, or subscription tiers at a glance

Designed to IP68 Standards

Designed to IP68 Standards

Built to IP68 ingress protection standards — protected against dust, moisture, and sweat in outdoor charging environments

Reduced Card Reissuance

Reduced Card Reissuance

Durable replacement for disposable EV charging cards — built to outlast standard plastic credentials and reduce reissuance costs over time

Who uses NFCKEY:

  • NFCKEY is carried and used by drivers and fleet users as a wearable NFC EV charging credential
  • Drivers present NFCKEY to the charger reader to authenticate and start a charging session, in the same way as a traditional RFID charging card

Who manages NFCKEY:

  • NFCKEY is issued, enrolled, and managed by the charging point operator, mobility service provider, fleet operator, or system administrator operating the EV charging platform
  • Drivers do not configure, program, or manage EV charging credentials themselves

All charging authorisation, session control, billing decisions, and credential management remain fully system-controlled within the EV charging management platform. NFCKEY cannot be self-configured by drivers — chip compatibility depends on the operator's charging infrastructure.
