I normally travel to work in Westminster from Cambridge on one-day
Travelcards or day returns to King's Cross with bike. No interest in
oystercards there obviously.

However, from time to time I stay overnight at my parents' in Putney
and travel on a Network Awaybreak from Cambridge to either King's
Cross (with bike) or Underground Zones 1/2. In the latter case I need
to buy single tube tickets on top (mainly in the morning from Putney
when my Network Card isn't yet valid).

Can I use a fairly small amount of stored value on an oystercard for
these occasional journeys? I've never bought a carnet for Zone 1
trips because they are only valid for a year and I don't make 10
trips in that time.

Oyster Prepay would appear to meet your requirements. A £3 deposit is
required. It's not yet available for bus or Tramlink. No photocard
necessary if bought at a Tube station. All that info is quoted
direct from the Web site ...

Thanks, that appears to meet my requirements. Is there really no minimum
amount stored if bought at a tube station? Or is that because a tube
station is then the only place where additional credits (below the £10
online minimum) can be made?
