# NFC Transaction Module

The NFC Transaction Module embedded within Eryon enables fast, secure, and fully on-chain payments through simple tap-based interactions. Designed for both utility and minimal friction, this system turns the ring into a self-contained payment interface that integrates seamlessly with real-world crypto commerce.

When brought within proximity of a compatible NFC reader, the ring initiates a transaction handshake. This interaction is authenticated by the user’s biometric signals and signed by the secure enclave within the ring, ensuring that only the legitimate owner can authorize payments. No screens, PINs, or manual wallet approvals are required.

* **Tap-to-Pay Execution:** Instantly initiates crypto transactions with physical proximity.
* **Biometric-Secured Signing:** Verifies the user before releasing any signed payload.
* **Multi-Token Support:** Enables payments in $EON and other supported assets.

This system allows Eryon to deliver a familiar, contactless experience while preserving full decentralization and user custody. Payments are executed on-chain with optimized gas models, and users can interact with vendors, peers, or DeFi endpoints using nothing more than a tap of the ring.
