In the future, molecular femtosecond laser techniques could potentially be used to mark cards with subatomic precision by:
1. Femtosecond laser pulses: These ultra-short pulses can interact with molecules at extremely high speeds, allowing for precise control over the structure and properties of the cards.
2. Subatomic marking: By using the precise control provided by the femtosecond laser, it may be possible to mark individual atoms or subatomic particles within the molecular structure of the cards, creating microscopic marks that are virtually impossible to detect without specialized equipment.
