Interactive ID Server for Campus NFC Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current student ID systems on university campuses operate in a unidirectional manner, failing to provide real-time information back to students after their ID cards interact with readers, and there is no integration with next-generation NFC devices for enhanced functionality.
Innovation Solution
An interactive ID server that uses NFC tags and readers on mobile devices to receive and process tag and reader IDs, enabling the dynamic delivery of content such as messages, URLs, and notifications to mobile devices via a network interface, integrating with existing legacy systems without requiring forklift replacements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional unidirectional ID card system is used, then the system is simple and costs are low, but real-time information feedback to students is not provided
Solution Approach 1:
The patent implements a feedback mechanism where the ID server sends real-time information back to the student's mobile device after an NFC interaction. When a student touches their ID card to a reader, the system not only processes the access control or payment but also automatically delivers relevant information (such as account balance, admission confirmation, or transaction details) to the student's smartphone, creating a closed-loop feedback system that resolves the information loss problem.
Solution Approach 2:
The patent makes the student's existing mobile device serve multiple functions: it acts as both the NFC card reader and the information display terminal. By integrating the NFC reader application on the student's smartphone with the ID server, the system eliminates the need for separate information display devices while enabling real-time feedback, thus improving information delivery without proportionally increasing system complexity.
2Adaptability or versatility
If next-generation NFC devices with mobile integration are implemented, then real-time information delivery is enabled, but integration with legacy systems requires additional infrastructure
Solution Approach 1:
The patent introduces an ID server as an intermediary component that bridges the legacy access control/payments system and the next-generation mobile NFC devices. The ID server receives NFC interactions from students' mobile devices, processes them through the existing legacy system, and then delivers enhanced information back to the mobile device. This intermediary approach enables integration without requiring complete replacement of legacy infrastructure.
Solution Approach 2:
The patent segments the system into distinct functional components: the legacy access control/payments system, the new ID server, and the student's mobile device with NFC reader application. This segmentation allows each component to operate independently at its own technical level while communicating through standardized interfaces, reducing integration complexity and enabling gradual deployment.
3Loss of information
If plastic ID cards with magnetic stripes are used, then the system is simple to operate, but no additional real-time information can be delivered to the student
Solution Approach 1:
The patent creates a functional copy of the traditional ID card system within the mobile device. The NFC reader application on the smartphone replicates the card-swiping operation by reading NFC tags, while simultaneously enabling the device to receive and display real-time information from the ID server. This copying approach maintains the simplicity of the original interaction model while adding enhanced information delivery capabilities.

Function Achieved in This Case
Enables two-way data operations, providing students with real-time information and interactive content, such as account balances, classroom materials, and social updates, while maintaining existing infrastructure and minimizing costs.
Implementation Method 1
a first near field communication (NFC) device coupled to a local area network of a campus, a mobile device of an authorized person of the campus having a second near field communication (NFC) device for communicating with the first NFC device
Data Source
AI summary
An interactive ID system enables dynamic delivery of content to a mobile device of a person on a campus. The system includes an interactive ID server coupled to receive a tag ID of a near field communication (NFC) tag and a reader ID of an NFC reader in communication with the NFC tag, in which one of the NFC tag and the NFC reader is on the mobile device and either the tag ID or the reader ID is associated with the person. The interactive ID server determines and communicates the content provided to the mobile device.
