The gates at London Bridge on the National Rail platforms will let

be
used even if you have already touched in or out there.

That could be useful to know, if only to avoid putting my season
ticket
through the gates.

Frequent use may well be monitored to stop "dumb-belling".

What does 'dumb-belling' mean?


"Dumb-belling" or short ticket fraud is where somebody uses passes
valid solely at each end of a long journey to pass through gatelines.
For example holding a Z1 travelcard and a Z6 travelcard, and making
regular Z1-6 journeys. Gates can be set to monitor this with paper
tickets, and I imagine on Oystercards too.
