Six Technologies in One Card
Ultra-Thin Smart Card Structure
The Cardnation IoT card adheres to the universal ISO/IEC 7810 ID-1 standard, ensuring compatibility with all existing card infrastructure worldwide. At just 0.84mm thick, it fits naturally in any wallet while housing a complete IoT ecosystem inside.
BLE Connectivity
Bluetooth Low Energy (BLE) technology enables continuous, energy-efficient connection between the IoT card and the user's smartphone. When separation is detected, instant alerts are triggered on both devices.
Wireless Charging Technology
The world's first Qi-compatible wireless charging IoT card. Simply place the card on any Qi charging pad — the same pad used for smartphones — and the internal thin-film battery recharges automatically.
NFC & Payment Integration
Full NFC and EMV compliance enables the IoT card to function as a complete payment instrument. Integration with financial institutions, transportation networks, and authentication systems.
Bidirectional Alert System
The bidirectional alert system creates a safety loop between card and smartphone. When the card moves beyond the configured proximity threshold, the smartphone immediately alerts the user.
Smart Platform Connectivity
The Cardnation platform integrates with Samsung SmartThings, enabling the IoT card to participate in the broader smart home and smart city ecosystem.
How It Works
BLE Pairing
The IoT card connects with the smartphone through Bluetooth Low Energy. The initial pairing takes seconds and maintains a persistent, energy-efficient connection.
Separation Alert
If the wallet or card is left behind, the smartphone immediately sends an alert. The user can see the last known location on the app map.
Community Detection
Nearby smartphones with the app installed can anonymously detect the BLE signal and update the card location — without revealing any personal information.
Family Safety Sharing
Users and family members can optionally share safety location information. Ideal for elderly parents, children, or anyone who needs an extra layer of protection.
