Barcode Contact Exchange via Camera Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional business cards are prone to loss, damage, and inefficiency in exchanging contact information, necessitating improved methods for short-range contact information management.
Innovation Solution
The use of electronic handheld devices equipped with cameras and memory for encoding and decoding barcodes to transmit and receive contact information, enabling secure and efficient exchange through barcode scanning and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional paper business cards are used for contact information exchange, then the method is simple and universally compatible, but the contact information is prone to loss, damage, and inefficiency
Solution Approach 1:
The patent replaces physical business cards with digital contact information stored in electronic devices. The camera captures an image of a barcode (digital copy of contact data), which is then decoded to extract contact information, eliminating the need for physical card handling while preserving the exchange function
Solution Approach 2:
The patent substitutes the mechanical process of physically handling and writing down contact information from paper cards with an automated optical system. The camera captures the barcode image, the processor decodes it automatically, and the contact information is extracted without manual intervention, replacing mechanical card handling with automated digital processing
2Productivity
If manual writing and recording of contact information is used, then no additional devices are needed, but the process is time-consuming and error-prone
Solution Approach 1:
The patent replaces manual writing and recording with an automated optical-digital system. The camera captures the barcode image, the processor automatically decodes it using optical recognition, and the contact information is extracted and stored digitally, eliminating manual transcription entirely
Solution Approach 2:
The system performs the entire contact information extraction process automatically without human intervention. The camera self-captures the barcode, the processor self-decodes the image, and the system self-extracts and stores the contact data, making the process self-service and highly efficient
3Reliability
If physical business cards are exchanged, then visual verification of the other party is possible, but the cards can be lost or damaged easily
Solution Approach 1:
The patent creates a digital copy of contact information through barcode encoding. The contact data is transformed into a visual barcode that can be captured by the camera, providing both visual verification (like physical cards) and digital durability (immune to loss or damage), resolving the contradiction between security and convenience
Data Source
AI summary
A method and device exchanging contact information on an electronic device. Contact information is obtained from a contact by scanning a barcode using an electronic device and decoding the barcode to recover the contact information encoded therein. The contact information may be used to reciprocate by sending user contact data in a message addressed to an electronic address obtained from the contact information. The user contact data may be encoded in a second barcode displayed on the electronic device.
