Suspended microchannel resonators could potentially enable the undetectable card marking of subatomic surface defects by:
1. Resonant frequency shift: The resonant frequency of a suspended microchannel resonator can change when a subatomic surface defect is introduced on the card, allowing for the detection of marked cards using a specialized reader device.
2. Quantum tunneling: By using quantum tunneling techniques, the subatomic surface defects can be detected without the need for physical contact with the marked cards, making the marking process undetectable.
