The report by 404 Media described how anybody with entry to a bank card quantity that one other particular person might need used to tap-and-pay for subway rides might then use the cardboard to trace the person’s motion on the subway system.

A Stalking Risk
OMNY’s journey historical past info reveals solely the purpose of entry into the subway system, not the exit level. Even so, the information is sufficient for an abuser to stalk victims or for somebody to trace a person or slender down the place they could stay, the 404 Media article warned.
