BLE Wireless Link for Real-Time Line Item Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Near Field Communication (NFC) requires close proximity and has a short connection time, limiting the ability to display line item data in real-time during in-store wireless transactions.
Innovation Solution
Bluetooth Low Energy (BLE) protocol enables a longer-range, continuous wireless connection, allowing for real-time transmission and display of line item data during transactions, eliminating the need for constant device proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NFC protocol is used for wireless transactions, then close proximity connection is established, but connection time is limited and real-time data transmission is prevented
Solution Approach 1:
The patent changes the communication parameter from NFC (Near Field Communication) to Bluetooth Low Energy (BLE), which allows the connection to maintain stability while extending the duration from seconds to minutes or hours, enabling real-time data transmission throughout the shopping experience
2Reliability
If NFC protocol is used for wireless transactions, then secure close proximity connection is established, but user mobility is restricted requiring constant device holding
Solution Approach 1:
The patent transitions from NFC's close-proximity requirement to BLE's extended range capability, allowing users to move freely within tens of meters while maintaining a secure connection, eliminating the need to constantly hold the device near the access point
Solution Approach 2:
The system uses BLE as an intermediary communication layer between the mobile device and the access device, enabling reliable data transmission over longer distances without requiring direct physical proximity, thus improving user convenience while maintaining connection security
3Productivity
If NFC protocol is used for wireless transactions, then transaction processing is completed, but real-time line item data display is prevented due to short connection window
Solution Approach 1:
The patent establishes a continuous BLE connection that persists throughout the entire shopping and transaction process, allowing line item data to be transmitted and displayed in real-time as items are scanned, rather than being delayed until after transaction completion
Solution Approach 2:
The system transmits line item data to the user's device in advance during the shopping phase, allowing users to review items before finalizing the transaction, enabling informed purchasing decisions without delaying the checkout process

AI summary
Methods for wireless payments using the Bluetooth low energy (BLE) protocol are provided. A first method includes establishing a wireless-short range communication link from a communication device to a peripheral device associated with an access device. The communication device receives item level data associated with an item being processed by the access device. The communication device displays the item level data associated with the item and transmits payment data to the access device. A second method includes establishing wireless-short range communication link to from a peripheral device associated with an access device to a communication device. The peripheral device transmits item level data associated with an item being processed by the access device, wherein the communication device displays the item level data associated with the item and receives payment data from the communication device.
