Whether that 'logical engine' would be able to cope with people going

What about more than one person using the same card? I use my credit card
to buy tickets for all the family quite often.

A very good question. I suspect they'll have a slogan like "Travel on
the tube with Mastercard, if everyone in your party has one; For
everything else, there's Oyster".

I don't think it'd be any different to Oyster - any one credit/debit
card could only be used in this way by one person at any one time (and
strictly speaking at least I'd expect it should only be the named
cardholder).

Multiple (regular, paper) tickets could still be purchased in one
transaction using a debit/credit card from the ticket office or ticket
machine.

People using the wrong card to get through a gate - or erroneously
using a card when they've already got a paper ticket - is an obvious
issue one can foresee about this development.

Children with credit/debit cards? Doesn't sound likely to me.

Whoosh! (They are the "everything else".)

Debit cards for the under-age, no credit history, don't trust
themselves etc do exist.

Solo is one.

They are designed to be unable to create an overdraft so can't be used
if the bank link isn't operational - no falling back to signatures &
multipart forms with embossing machines during a power cut.

However they are probably not allowed for wave and pay applications.

Rather destroys the pay-wave system for adults with children then.

So, the advantage for casual users of not needing to get Oyster for their
occasional visit to London because they can use paywave disappears if they
have children with them. Terrific!

I'm not sure how you could implement a "one-wave many-people" system.

It's marginally better than being stuck with a one-system proprietary
card (ie Oyster), but raises the stakes such that international road
warriors will need a pay-wave card in their armoury.

I wonder if a bank issuing an internationally-enabled pay-wave card will
be able to resist the temptation of adding a hefty "foreign transaction
charge" every time it's used. If you are stuck at the airport and need
to get to the hotel, it's likely to be cheaper than a taxi, but for
regular journeys the cost soon adds up.

Pay wave can only be used for a purchase of up to £15 (only recently
increased from £10), so it's not really suitable for purchasing multiple
tickets.
