Talk:Oyster card/to do


 * Issues (technical setbacks and criticisms) needs to be checked for NPOV and verifiability.


 * Has it actually been used by the police yet to trace movements? (Security services unlikely to confirm or deny.) What is the official policy regarding this?


 * The PAYG system changed in November so £4 (£5 on specific NR journeys) is debited at start of journey and the difference is credited back at the end. This applies a maximum cash fare to those who do not touch out.


 * Bus passes bought at tube stations are only on Oyster soon (there is a poster). Need to find details for citation.
