Fleet Authentication
DESFire EV3 cards with AES-128 encryption for commercial fleet charging. Each card carries a unique diversified key tied to the driver's identity, enabling per-vehicle kWh tracking and HMRC-compliant expense allocation. Cards authenticate via OCPP Authorize.req against your Central System in under 500ms.

Network Roaming
One RFID card, 900+ charging networks. Our cards are configured for OCPI (Open Charge Point Interface) and OICP (Open InterCharge Protocol) roaming, working with Hubject, Gireve, and e-clearing.net platforms. The card's idTag is registered across roaming hubs, enabling real-time authorization at any participating station regardless of the CPO.
Smart Charging Access
RFID-based access management for public and semi-public charging stations. Cards authenticate at the station reader via ISO 14443A, triggering an OCPP StartTransaction sequence. The Central System logs session start/stop times, energy consumed, and calculates billing — all tied to the card's unique identifier for auditable records.
