Solution Overview

Problem

Transaction cards, such as debit and credit cards, are static entities that require replacement if the card number is compromised, involve risks during mailing, and need customization, leading to increased time and cost.

Innovation Solution

Integrating low-power displays with contact pads on transaction cards that can be wirelessly powered and updated using energy from wireless communication, allowing for dynamic display of information without constant power supply.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a display is added to a transaction card to enable dynamic information updates, then the ability to update account information is improved, but the power requirement increases

Engineering Contradiction:

Improveability to update account informationVSAvoidpower requirement

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The display is updated periodically through wireless communications during transactions rather than continuously. The contact pad receives power and data in periodic bursts when the card is used, updating the display at these intervals rather than maintaining continuous operation.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The transaction card's existing contact pad infrastructure is utilized to power and update the display, eliminating the need for a separate power source. The card's normal transaction processing functions double as the power delivery mechanism for the display.

Inventive Principle:

Principle #25Self-service

2Reliability

If physical reissuance of cards is required when account information changes, then security is improved, but the loss of time and productivity increases

Engineering Contradiction:

ImprovesecurityVSAvoidtime for card reissuance

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The display on the card can be pre-loaded with updated information through wireless communication before the card is returned to the user. This allows information updates to occur in advance during transaction processing, eliminating the need for physical reissuance.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The mechanical process of physical card reissuance is replaced with wireless electronic updates to the display. Instead of manufacturing and mailing new cards, the contact pad transfers data wirelessly to update the display, substituting a mechanical system with an electronic one.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If contact pads on transaction cards are used to power displays, then device complexity is reduced, but the available power for display updates is limited

Engineering Contradiction:

Improveredesign requirementVSAvoidavailable power for display

Core Design Contradiction:

Device complexityVSPower

Solution Approach 1:

The display is updated partially or incrementally using the limited power available from contact pad communications. Rather than requiring full power for complete updates, the system performs partial updates or selects which information to display based on available energy.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Exemplary embodiments relate to updatable displays for transaction cards, such as credit cards or event passes. The displays may be, for instance, an electrophoretic or memory liquid crystal diode display. The transaction card may include a contact pad capable of engaging in wireless communication. Information may be exchanged between the transaction card and a mobile device or terminal, where a processor on the mobile device processes the received information to generate displayable information. The processor updates the display with the displayable information. The contact pad may be electrically connected to the display, and the display may derive electrical power to perform the updating from the wireless communication. For example, where the wireless communication is a near field communication (NFC), a radio frequency field may be generated that supplies enough power to run the processor and at least partially update the display.
