Quantum Secure Authentication (QSA) takes advantage of how single photons of light move under certain conditions to create patterns on the back of payment cards that are impossible to reproduce. The approach can be used for identity vetting or to verify the authenticity of debit and credit cards, a trade association for optics and photonics professionals says. With QSA, any attempt to get at the data will only succeed in destroying it, an attacker would destroy the information stored on the card, the Optical Society says.”]
