Printer Payment via Device ID and NFC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in securely and conveniently paying for content from printers, especially in public settings where entering credit card information is a security risk and a hassle.
Innovation Solution
Printers use Near Field Communication (NFC) to receive device identification information from users' computing devices, such as IMEI or SIM numbers, which is then sent to a content management server to facilitate payment through associated service providers, eliminating the need for users to input payment information directly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users enter credit card information directly into the printer or print application, then payment can be processed, but security risks increase and user convenience decreases
Solution Approach 1:
The patent introduces an intermediary payment system where device identification information (IMEI, SIM number) serves as a mediator between the user and the payment processing system. Instead of directly entering credit card information into the printer, the system uses the computing device's identification as an intermediary key to retrieve payment information from the service provider, thereby enhancing security while maintaining convenience
Solution Approach 2:
The patent extracts the sensitive payment information entry process from the printer and print application interface. By removing the direct input of credit card details from the user interface and replacing it with automatic device identification-based payment, the system eliminates the security vulnerability of exposing payment entry fields while preserving the payment functionality
2Adaptability or versatility
If the printer connects to a content management server for content delivery, then content selection and delivery is facilitated, but the complexity of the payment system increases
Solution Approach 1:
The patent implements a universal payment mechanism that works across multiple contexts (different printers, content types, service providers) through a single approach: using device identification information. This multi-functional payment system integrates with the content management server infrastructure without requiring separate payment mechanisms for different scenarios, thereby managing complexity while enhancing versatility
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
This method provides a secure and user-friendly payment process by leveraging device identification information for payment, reducing security risks and eliminating the hassle of entering payment details, allowing for seamless content delivery, such as printing images or applications.
Implementation Method 1
The printer and computing device can be in close proximity, such that communication between the devices is via Near Held Communication (NFC)
Data Source
AI summary
A technique performed by a printer includes receiving identification information from a computing device. The identification information may be sent to a server, such as a content management server. The identification information can be used for payment. Payment confirmation, authorization to provide content, or content itself may be received from the server.
