Solution Overview
Problem
Existing NFC communication systems struggle to perform both first and second near field communication modes simultaneously with a terminal device, leading to inefficiencies in user authentication and printing processes.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If both first and second near field communication are performed by passing a terminal device once, then communication efficiency is improved, but communication protocols become more complex
Solution Approach 1:
The patent segments NFC communication into two distinct modes: first NFC communication (Card Emulation mode) for user identification and second NFC communication (P2P mode) for device identification and printing. This segmentation allows each communication type to use its own optimized protocol while achieving both functions in a single terminal device pass, thereby improving communication efficiency without requiring a single complex unified protocol.
Solution Approach 2:
The patent implements periodic action by sequentially executing first NFC communication followed by second NFC communication as the terminal device passes over the NFC reader. This periodic/sequential execution allows the system to perform multiple communication tasks in a structured sequence during a single pass, enhancing productivity while maintaining protocol clarity through temporal separation.
2Measurement precision
If user identification is acquired via first near field communication and device identification is transmitted via second near field communication, then authentication accuracy is improved, but communication time increases
Solution Approach 1:
The patent applies preliminary action by first acquiring user identification through Card Emulation mode before proceeding to P2P mode communication. This preliminary authentication step ensures accurate user verification is completed first, establishing a foundation for subsequent printing operations. The sequential arrangement optimizes time by preparing authentication data in advance during the terminal device pass.

AI summary
An information processing apparatus includes a first near field communication unit that transmits a first wireless signal for performing first near field communication; a second near field communication unit that transmits a second wireless signal for performing second near field communication; and a communication control unit that controls the first and second near field communication units such that the first wireless signal and the second wireless signal are alternately transmitted, identification information of a user is acquired from a terminal device via the first near field communication when connection via the first near field communication is established in response to transmitting the first wireless signal, and identification information of the information processing apparatus is transmitted to the terminal device via the second near field communication when connection via the second near field communication is established in response to transmitting the second wireless signal.
