Solution Overview

Problem

Existing payment cards lack effective mechanisms to prevent inadvertent activation and data transmission, leading to potential errors and unauthorized transactions.

Innovation Solution

Incorporating a locking feature that requires a specific sequence and duration of button presses to awaken the card, with a stored unlocking code ensuring only authorized data transmission to magnetic stripe readers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the card is made easily operable with simple button presses, then ease of operation is improved, but reliability deteriorates due to inadvertent activation and unauthorized transactions

Engineering Contradiction:
Improveease of operationVSAvoidreliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies preliminary action by requiring a specific sequence of button presses (wake-up sequence) before the card becomes operational. The processor monitors the sequence and duration of button presses in advance, and only allows data transmission after verifying the correct sequence has been completed. This prevents inadvertent activation while maintaining ease of use for authorized operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by having the processor monitor and verify the button press sequence in real-time. The system provides feedback by detecting the presence of a communications device and confirming the correct wake-up sequence was executed before enabling data transmission. This feedback mechanism ensures reliability while allowing straightforward operation for authorized users.

Inventive Principle:
Principle #23Feedback

2Reliability

If a locking feature requiring specific button sequence is implemented, then reliability is improved by preventing inadvertent activation, but device complexity increases

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies self-service by having the processor automatically monitor, detect, and verify the button press sequence without requiring external intervention. The system self-manages the locking and unlocking states based on the detected sequence, eliminating the need for complex external locking mechanisms while maintaining high reliability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements multi-functionality by having the processor perform multiple functions: monitoring button presses, detecting communications devices, verifying wake-up sequences, and controlling data transmission. This consolidates what could be separate complex components into a single processor, reducing overall device complexity while maintaining reliability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Use of energy by moving object

If the card remains in sleep mode to conserve energy, then energy efficiency is improved, but ease of operation deteriorates due to additional activation steps required

Engineering Contradiction:
Improveenergy efficiencyVSAvoidease of operation
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The patent applies preliminary action by establishing a clear wake-up sequence that the user must perform to activate the card from sleep mode. The processor monitors for this specific sequence and automatically transitions the card to operational state, reducing the need for additional manual steps while maintaining energy efficiency during sleep mode.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback by having the processor detect the wake-up sequence and provide automatic confirmation before enabling full operation. This feedback mechanism streamlines the activation process, making it easier for users while maintaining the energy-saving benefits of sleep mode.

Inventive Principle:
Principle #23Feedback

AI summary

Cards may be provided with locked modes of operation. A card may, for example, monitor a particular sequence of one or more manual inputs while the card transitions from a low-power mode of operation to a locked mode of operation. The card may store the particular sequence of the one or more manual inputs as a locking code. The card may ignore subsequent manual inputs during the locked mode of operation until the locking code is reentered into the card. Once the locking code is reentered into the card, the card may again become reactive to manual inputs received by the card.
