Dynamic Offline Balance Management for Preauthorized Smart Cards

The patent implements dynamic balance management where the preauthorized offline balance is no longer fixed but adjusts automatically based on environmental conditions. The system detects whether the cardholder is in an offline environment (e.g., underground, metro, subway) and dynamically redistributes the total balance between online and offline portions, making the whole balance available when needed while maintaining offline transaction capability.

The patent changes the parameter of offline balance from a fixed value to a dynamic value that adjusts based on environmental parameters. The system monitors environmental conditions (such as location, network availability) and modifies the offline balance parameter accordingly, allowing optimization for specific environments while maintaining a stable baseline structure through default values.

The patent transforms the static balance reset mechanism into a dynamic redistribution system. Instead of simply resetting offline balance to a fixed predetermined value, the system dynamically calculates and redistributes the total balance based on current environmental conditions and transaction patterns, ensuring optimal availability across both online and offline channels.

The patent applies preliminary action by proactively managing the offline balance before depletion occurs. The system monitors offline balance levels and environmental conditions, and performs balance redistribution in advance through online transactions when conditions are favorable, ensuring that sufficient offline balance is available before needed without waiting for depletion and subsequent authorization delays.
