NFC Sensory Totem Badge with Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional badges fail to fully convey their substantial meaning, commemorative value, and stories, and they lack security features to prevent unauthorized access to the information they transmit.
Innovation Solution
A sensory totem badge equipped with an NFC chip and coil, storing individualized information such as text, sound, short films, or URLs, which can be accessed via a mobile device, and includes a private authentication module to ensure secure and authorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If NFC technology is added to the badge to enable information transmission, then the badge can convey substantial meaning and commemorative value, but privacy and security risks arise from unauthorized access
Solution Approach 1:
The patent introduces an NFC tag as an intermediary device between the badge and mobile devices. The NFC tag stores encrypted authentication information and acts as a mediator that controls information access. When a mobile device approaches the badge, the NFC tag verifies authentication credentials before allowing access to commemorative information, thus enabling information transmission while maintaining security through this intermediary layer.
2Reliability
If authentication mechanisms are implemented to prevent unauthorized access, then security is improved, but the complexity of the badge system increases
Solution Approach 1:
The patent extracts the authentication functionality from the badge itself and places it in the NFC tag. The NFC tag contains the authentication mechanism separate from the main badge structure, allowing security features to be implemented without significantly complicating the badge design. The authentication data is stored in the NFC tag rather than being integrated into the badge's core components, thereby maintaining simplicity while enabling security.
3Loss of information
If the badge stores detailed commemorative information, then its value and meaning are enhanced, but the badge loses power supply capability for continuous operation
Solution Approach 1:
The patent extracts the information storage function from the badge and places it in the NFC tag. The NFC tag stores all commemorative information, text, images, and multimedia data without requiring power supply to the badge itself. The badge only needs to provide the NFC tag and trigger the information transfer when approached by a mobile device, eliminating the need for batteries or power sources in the badge while maintaining full information storage capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The badge effectively transmits and displays commemorative information, enhancing its value and security by allowing only authorized access, thereby improving user experience and privacy.
Implementation Method 1
a near field communication (NFC) technology is applied to transmit data between electronic devices, and these applications include those of an IC card (including a credit card for shopping), IPASS, access security and control, and a ticket

AI summary
A sensory totem badge capable of transmitting individualized information and includes: a totem badge body attached or sewed onto an object surface; an e-tag, installed to the totem badge body, and including an NFC chip and an NFC coil; and a totem individualized information, stored in the e-tag or a cloud server; such that when a mobile sensing device is near the e-tag of the totem badge body, the implication represented by a totem on the totem badge body, the story behind it, or private words can be read. Therefore, the totem badge body is given with intangible specificity and commemoration to achieve higher value and sense of technology.
