Radioactive alpha-recoil spectrometry (RARS) techniques can uniquely identify and track individual playing cards by:
1. Card marking: RARS involves marking the cards with a radioactive isotope that decays through alpha-recoil, emitting alpha particles that can be detected by a specialized spectrometer.
2. Spectral analysis: The emitted alpha particles can be analyzed by the spectrometer, which can identify the unique spectral signature of each card, allowing for the tracking of individual cards as they are played or shuffled.
