No, you cannot use the same physical card or mobile device for two different people at the exact same time when entering the NYC subway or bus via the OMNY (One Metro New York) system. OMNY is designed as a "Pay-Per-Ride" and "Fare Capping" system that tracks individual journeys to provide a free weekly pass after 12 rides. If you tap your card and then immediately try to tap it again for a second person, the reader will typically display a "Just Used" or "Pass Not Allowed" message to prevent fare sharing and accidental double-charging. This is a "high-fidelity" security feature intended to ensure that the system can accurately calculate your progress toward the weekly fare cap. If you are traveling as a pair, each person must have their own unique payment method—such as one person using a physical credit card and the other using Apple Pay on their phone (even if linked to the same bank account), as these are recognized as separate "tokens" by the OMNY readers. This ensures that both travelers receive the correct fare treatment and can benefit from the system's automated discounts independently.
