Not sure if anyone has noticed this, but NJ Transit seems to have slightly redesigned the look of their rail tickets. My tickets to and from New York Penn that I printed out last Friday have a QR code on top. I tested scanning these with the QR reader at the faregates in Secaucus and they worked to open the gate. This will be nice for those with monthly tickets as it will negate the need to take the ticket out of it's wallet or holder as long as the QR code is visible.
