Solution Overview
Problem
Conventional devices using GPS or wireless communication networks struggle to provide location-based services with precise location values, such as room numbers or famous local places, and cannot deliver services tailored to specific locations.
Innovation Solution
A system and method utilizing NFC tags to receive tag information, which includes location details, to request and provide location-specific services from a server, allowing devices to receive service data corresponding to the tag information and application type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS or wireless communication network is used to track device location, then location tracking is achieved, but precise location values including room number and famous local place cannot be provided
Solution Approach 1:
The patent introduces NFC tags as intermediary elements deployed at specific locations (rooms, places) to bridge the gap between coarse location tracking and fine-grained location identification. The NFC tags act as mediators that provide detailed location information when activated by the mobile device, enabling both GPS-level tracking and room-level precision without requiring complex infrastructure changes.
2Adaptability or versatility
If conventional location tracking methods are used, then basic location information is obtained, but services tailored to specific locations cannot be provided
Solution Approach 1:
The system performs preliminary actions by pre-deploying NFC tags at specific locations with associated service information before the user arrives. When the user approaches a location, the pre-positioned NFC tag activates and provides location-specific services immediately, enabling tailored services without requiring real-time processing or complex infrastructure.
3Measurement precision
If NFC tags are deployed to provide detailed location information, then precise location-based services are enabled, but system complexity increases
Solution Approach 1:
The patent employs inexpensive NFC tags that can be easily deployed and replaced as the preferred solution for location identification. These low-cost tags provide detailed location information without requiring complex infrastructure, making the system economically viable and easier to implement compared to expensive GPS-denied indoor positioning systems or complex wireless network triangulation setups.
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
Enables effective provision of location-based services by determining the detailed location of an NFC tag and providing different services based on the tag information, enhancing the accuracy and relevance of services delivered to the device.
Implementation Method 1
NFC is a type of Radio Frequency IDentification (RFID) technology that utilizes contactless near field wireless communication through which a device, e.g., a mobile phone, a smart phone, a Personal Digital Assistant (PDA), a notebook, etc., and transceives data within a distance of 10 cm using low power and a predetermined frequency band

AI summary
A system and method of providing a service using a Near Field Communication (NFC) tag are provided. A device that receives the service includes a tag information receiving unit that receives tag information from the NFC tag; a service requesting unit that provides a server with application information about an application that is installed in the device and the tag information, and that requests a service corresponding to the application; and a data receiving unit that receives service data from the server. The service data corresponds to the application information and the tag information and differs from another service data, according to a type of the application.
