NFC Terminal Mode Switching for High-Speed Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses with NFC terminals face complexity in communication control for data acquisition from mobile terminals, as they primarily function as card readers and are not efficient in transferring large amounts of data at high speeds.
Innovation Solution
The apparatus includes a non-contact communication device that switches between reader mode and inter-device communication mode upon receiving a transmission request, allowing for efficient data transfer between the information processing apparatus and mobile terminals via NFC, enabling bi-directional data communication and simplifying communication control.

Engineering Contradiction Analysis
1Productivity
If the NFC terminal functions as a card reader for reading information from portable terminals, then it can read authentication information, but it cannot supply large amounts of data to mobile terminals at high speed
Solution Approach 1:
The NFC terminal dynamically switches between reader mode and inter-device communication mode based on the communication requirements. When large data transfer is needed, it transitions to inter-device communication mode; when reading authentication information is needed, it operates in reader mode. This dynamic mode switching enables the system to adapt to different communication scenarios and achieve high-speed data transfer when necessary.
2Device complexity
If the NFC terminal only operates in reader mode, then the device structure remains simple, but communication control becomes complicated for data acquisition from mobile terminals
Solution Approach 1:
The NFC terminal is designed with multi-functionality, capable of operating in both reader mode and inter-device communication mode. This universal design allows the same hardware to perform different communication functions based on software control, enabling efficient data acquisition from mobile terminals without adding separate hardware interfaces while maintaining relatively simple device structure.
3Productivity
If additional interfaces are added for high-speed data transfer, then data transfer speed improves, but the device structure and communication control become more complex
Solution Approach 1:
Instead of adding physical interfaces, the system changes the operational parameters and communication protocols of the existing NFC terminal. By switching between reader mode and inter-device communication mode, the system achieves high-speed data transfer capability using the same physical interface, thereby improving data transfer speed without increasing device structure or interface complexity.

AI summary
According to an embodiment, an information processing apparatus includes a non-contact communication device and a processor. The non-contact communication device performs non-contact communication in a reader mode or an inter-device communication mode. The processor switches the non-contact communication device to the inter-device communication mode when transmission request information for requesting transfer of specific information is set in an electronic message received by the non-contact communication device in the reader mode from a second non-contact communication device, and cause the non-contact communication device that is switched to the inter-device communication mode to transmit the electronic message including the information requested in the transmission request information to the second non-contact communication device.
