Close. It's a (Retired staff) Privilege
Ticket Authority Card.
Thread title has now been amended.
A (Retired staff) Privilege Ticket Authority Card ("PTAC") gives 75% discount on equivalent pay as you go fares on Tube, DLR, London Overground, TfL Rail and National Rail services for leisure travel only.
You can normally only apply for a "PTAC" if you were formerly in service with London Transport (excluding staff employed by London Buses), London Regional Transport, or Docklands Light Railway before 1 April 1996, and are now aged 50+.
