Active Stored-Value Smart Card Peer-to-Peer NFC Transactions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stored-value smart cards require external devices for transactions, limiting their ability to facilitate direct peer-to-peer transactions between two cards.
Innovation Solution
Implementing active NFC-enabled stored-value smart cards with embedded batteries, microprocessors, and keypads that allow for secure, contactless communication and transactions between two active cards by verifying PINs, confirming card IDs, and completing transactions independently of a POS device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional stored-value smart cards use passive NFC chips without batteries, then the card structure remains simple and manufacturing cost is low, but the card cannot initiate transactions or communicate actively with other cards
Solution Approach 1:
The patent transforms the static NFC card into a dynamic active device by incorporating a battery. This enables the card to switch between being a passive target and an active initiator of NFC transactions, allowing the card to dynamically control when and how transactions occur without requiring external power sources
Solution Approach 2:
By embedding a battery and active NFC reader, the stored-value card becomes self-sufficient and can independently initiate transactions, verify PINs, and communicate with other cards without requiring a POS device or external power source, enabling peer-to-peer transaction capability
2Productivity
If stored-value cards require a POS device for transactions, then transaction security can be managed centrally, but the transaction process becomes slower and less convenient
Solution Approach 1:
The patent extracts the transaction processing capability from the external POS device and embeds it directly into the stored-value card through an active NFC reader and microprocessor. This allows the card to complete transactions independently by verifying PINs and processing payments directly with another card, eliminating the need for external device intervention and significantly reducing transaction time
3Reliability
If passive NFC cards are used, then power consumption is minimal and the card can be recharged via NFC, but the card cannot perform active authentication or initiate secure transactions
Solution Approach 1:
The patent incorporates a battery that is pre-charged and designed to power the active NFC reader and transaction processing functions. The battery enables the card to perform active authentication, PIN verification, and secure transaction initiation before any transaction occurs, ensuring reliability and security are established in advance rather than dependent on external power during the transaction
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
Enables direct, secure, and efficient peer-to-peer transactions between active stored-value smart cards, reducing the need for external devices and enhancing security through proximity-based communication and multi-layered encryption.
Implementation Method 1
Each of the first and second active SVSC may include an active NFC reader. The active NFC reader may be enabled to be active by using a battery embedded in each of the first and second active SVSC.
Implementation Method 2
NFC is a rapidly growing, short-range and wireless technology. Cards that include an NFC chip are enabled to passively transfer information stored on an NFC tag within the card to an NFC-enabled device
Data Source
AI summary
A method for performing a card-to-card direct contactless transaction between a first active stored-value smart card (“SVSC”) and a second active SVSC, each comprising an active near-field communication (“NFC”) reader. The method may include activating the first active SVSC by receiving input of a personal identification number (“PIN”) on a keypad located on the first active SVSC, verifying the PIN and further receiving input of a transaction amount on the keypad. The method may further include initiating a wireless NFC communication to perform the transaction by positioning the first active SVSC within a pre-determined distance to the second active SVSC and confirming accuracy of each of the first and second active SVSC using the active NFC reader to retrieve card ID data and confirm accuracy. Following confirming, the method may include directly completing the transaction between the first active SVSC and the second active SVSC.
