AI Technical Summary
Technical Problem
Existing payment card customization systems fail to effectively remove reserved areas while allowing user customization, leading to underutilization of card space and difficulty in determining allowed areas due to multiple restricted zones.
Method used
Implementing exclusion zones within the customizable area on smart cards and using the Separating Axis Theorem (SAT) to detect collisions between user-placed objects and reserved areas, prompting users to adjust object positions to avoid collisions.
Benefits of technology
Maximizes user customization area by ensuring no overlap with reserved zones, providing efficient and accurate collision detection, and enabling seamless customization without wasting space.

Abstract
Disclosed are a method and a system for detecting collision between at least two areas on a body of a smart card. Exemplary method comprises designating a first area, on the body of the smart card, where a user is allowed to customize by placing object(s). The method further comprises designating exclusion zone(s), within the first area, where customization by the user is prohibited. The method further comprises receiving a user input corresponding to placement of the object(s), detecting whether there is a collision between any exclusion zone(s) and any object(s), and in response to the detected collision, generating a prompt for the user to adjust a corresponding position of a colliding object within the first area to avoid collision with any of the exclusion zone(s).
