Single NFC Tap Multi-Transaction Linking Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional NFC systems require multiple taps for performing multiple transactions, such as ordering, redeeming coupons, and paying, which is cumbersome and time-consuming.
Innovation Solution
A system and method that enables multiple transactions through a single NFC tap by using a wireless device with a Secure Element (SE) memory storing Proximity Payment System Environment (PPSE) and Linked Payment System Environment (LPSE) applications, where linked Application Identifiers (AIDs) are processed via a single NFC tap, allowing simultaneous communication of order, coupon, and payment information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple separate NFC taps are used to perform multiple transactions (ordering, coupon redemption, payment), then each transaction can be processed securely and accurately, but the transaction process becomes cumbersome and time-consuming
Solution Approach 1:
The patent combines multiple separate NFC tap operations into a single tap by merging multiple application identifiers (AIDs) into one communication sequence. The system transmits a first AID for non-payment transactions and a second AID for payment transactions during a single NFC tap event, eliminating the need for multiple sequential taps and thereby improving transaction speed while maintaining security.
Solution Approach 2:
The patent implements preliminary action by pre-configuring the wireless device to store and manage multiple AIDs in a specific sequence before the NFC transaction occurs. The system prepares the transaction hierarchy (non-payment AIDs followed by payment AID) in advance, so that during the single NFC tap, the reader can automatically process them in the correct order without requiring additional user actions or multiple taps.
2Productivity
If a single NFC tap transmits multiple application identifiers, then transaction efficiency improves, but the risk of processing errors or security issues increases
Solution Approach 1:
The patent segments the multiple AIDs into distinct categories: non-payment AIDs (first AID) and payment AIDs (second AID). This segmentation allows the system to process different types of transactions separately within the same NFC tap event, maintaining clear boundaries between payment and non-payment operations. The reader processes each AID type according to its specific protocol, thereby maintaining transaction accuracy while improving efficiency.
Solution Approach 2:
The patent changes the parameter of AID transmission by encoding multiple AIDs in a specific hierarchical sequence (non-payment AID followed by payment AID) within a single NFC communication frame. This parameter change in transmission structure allows the reader to automatically distinguish and process different transaction types in the correct order, maintaining reliability while enabling single-tap multi-transaction capability.

Function Achieved in This Case
Facilitates quick and easy completion of multiple transactions by reducing the number of NFC taps required, enhancing the efficiency and speed of retail transactions.
Implementation Method 1
a wireless smart device may communicate with a wireless device reader using near field communication (NFC). In near field communication, a wireless smart device may communicate with a wireless device reader via inductive coupling of the reader antenna to the device antenna.
