Payment Card Service Selection via GUI and Touch Sensors

The payment card is designed to perform multiple functions beyond traditional payment processing. By integrating buttons or capacitive sensors, the card can trigger additional services such as game actions, check-ins, loyalty rewards, and other third-party applications. This multi-functionality allows a single card to serve both as a payment instrument and as a key for accessing various services, thereby improving adaptability without requiring separate devices for each function.

The system allows users to pre-associate additional services with specific buttons or capacitive sensors on their payment cards through a graphical user interface. Users can configure which services correspond to which buttons in advance, so that when they use the card at a point-of-sale terminal, the desired service is automatically activated without requiring any additional setup or configuration during the actual transaction. This preliminary configuration simplifies operation during use while managing setup complexity through user-friendly interfaces.

Instead of manufacturing complex physical buttons with intricate mechanical structures, the system uses capacitive sensors that can be integrated into the card's surface layer. These sensors detect touch inputs through changes in electrical capacitance rather than requiring physical protrusions or mechanical switches. This approach simplifies the manufacturing process while maintaining the functionality of buttons, as capacitive sensors can be manufactured using standard PCB fabrication techniques that are already widely used in the payment card industry.
