Near field communication activation and authorization

This describes a system where an NFC-enabled device, like a smartphone, first logs in and gets authorized over the internet using a public key and user credentials. Once this initial setup is complete, the device can then use its NFC function for various tasks, such as payments or access, without needing to log in again for each tap. The invention focuses on the NFC device itself performing these steps.

Why it matters: Filed before NFC payments and mobile authentication became ubiquitous. The infrastructure for secure, cloud-based pre-authorization and subsequent seamless NFC use is now mature.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedSoftware logic, secure network communication, cryptographic libraries.
