Forgive an equally naive supplementary: what is "capping" in this
context?

Individual fares are deducted from the balance until the daily 'capping'
level is reached. After that no more is deducted.

To take the simplest example, the off-peak Oyster bus fare is 80p. Make
one bus journey and 80p is deducted from your balance. Make another bus
journey and another 80p is deducted. Make a third bus journey and
another 80p is deducted, making £2.40 for the three journeys. Now comes
the clever bit - the daily cap for bus journeys is set at £3 - so,
you make a fourth journey and 60p is deducted. Nothing more would be
deducted for any further bus journeys on the same day.
