Dynamic Card System for Secure Transaction Authentication

The patent applies dynamics by transitioning from static card data to dynamic temporary card identification numbers that change over time. The card generates and displays different TCCNs for each transaction session, making the data dynamic rather than static. This resolves the contradiction by maintaining ease of operation (the card still works automatically) while improving security (fraudsters cannot use stolen static data because the data keeps changing).

The patent changes the parameter of card identification from fixed/static to variable/temporary. The card identification number is no longer a permanent attribute but changes based on time, transaction context, or security requirements. This parameter change allows the system to maintain operational simplicity while enhancing security through ephemeral credentials that expire or change regularly.

The patent extracts the power source from the card itself and relocates it to the external computing device. Instead of embedding a battery or power cell in the card (which would add complexity and mass), the card is designed to be powered externally during transactions. This extraction eliminates the need for internal power management components while maintaining the ability to operate for extended periods when connected to external devices.

The card is designed with multi-functionality by being able to draw power from various external sources (computing devices, terminals, etc.) rather than relying on a dedicated internal power source. The card can interface with different external power providers, making it universally compatible while reducing its own complexity. The external devices that already have power sources serve multiple functions including powering the card.

The patent applies preliminary action by pre-generating multiple temporary card identification numbers and storing them securely in the card's memory before they are needed. During transactions, the card can quickly retrieve and use pre-prepared TCCNs without needing to perform time-consuming decryption operations in real-time. This preliminary preparation reduces transaction time while maintaining security through the use of ephemeral credentials.

The patent merges the card's internal processing capabilities with external computing resources. The card performs lightweight operations locally (selecting and displaying TCCNs) while leveraging external devices for more computationally intensive tasks (generating encrypted card identification numbers, providing decryption keys). This distribution of computational load reduces the time burden on the card while maintaining security.
