Payment Terminal Receipt Transmission via NFC
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing payment methods using smartphones do not effectively transmit payment receipts to the user's communications terminal, leaving users uncertain about the transaction amount, especially when a physical receipt cannot be printed.
Innovation Solution
A method for immediate transmission of a transaction signal to the communications terminal, including building a data structure representing the receipt and transmitting it using NFC or BLE signals, ensuring real-time notification of transaction completion and providing a resource-locating address for receipt access, with encryption for security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical receipt is printed by the payment terminal, then the user has proof of payment, but the user cannot be sure the amount matches the initial amount when printing is not possible
Solution Approach 1:
The patent replaces the mechanical printing system with an electronic transmission system using NFC (Near Field Communication) technology. The payment terminal transmits the receipt data wirelessly to the user's smartphone, eliminating the need for physical paper receipts while ensuring the user receives accurate transaction information electronically.
Solution Approach 2:
The patent creates an electronic copy of the payment receipt and transmits it to the user's communications terminal. This digital replica contains all necessary transaction information (amount, timestamp, merchant details) and serves as valid proof of payment, replacing the need for physical paper copies.
2Loss of time
If the payment terminal transmits receipt data to the communications terminal, then the user receives immediate notification, but additional data transmission steps are required
Solution Approach 1:
The patent merges the receipt generation and transmission functions into the existing payment processing workflow. The same NFC communication channel used for payment authentication is utilized to transmit the receipt data, combining multiple functions into a single integrated process without requiring separate transmission hardware or protocols.
Solution Approach 2:
The patent prepares the receipt data structure in advance during the payment processing phase, before the actual payment completion. This preliminary preparation ensures that when the payment is authorized, the receipt can be immediately transmitted without additional processing delays, reducing overall time loss.
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
Ensures the user is immediately informed of the transaction details, enhancing transaction security and reducing user interaction, as the receipt is transmitted almost instantly and securely to the communications terminal.
Implementation Method 1
the use of an NFC-type very-short-range radio transmission
Implementation Method 2
or again the use of a specific device, that is an adjunct to the communications terminal
Data Source
AI summary
A method for processing transactions of the type including transmission, to a communications terminal, of a receipt relating to a payment transaction during the implementation of this payment transaction by a payment terminal. The method includes, in the payment terminal: obtaining a piece of data representing an end of a transaction; building a data structure according a piece of data of the transaction, the data structure representing a receipt; transmitting a signal including at least the data structure; subsequently to the step of transmission, finalizing the transaction, including the transmission of a piece of finalizing data to be transmitted to a user.
