My experience of card clash is an error 94 & the gates don't open.

But it's very worrying that they are charging the credit cards of people
not signed up to the trial. That seems to me to be completely wrong, on
many levels (for example, it means anyone can join the 'trial' just by
proffering their card).

The Metro story you referenced in the original post refers to buses -
CPC acceptance is not a trial on buses, it's been accepted as a fare
payment method since December 2012.

FWIW, trying my contactless credit card on validators (both on gates and
standalone) has resulted in an error message, can't remember which one.

There are now posters and signs around the transport network warning
against card clash, but I think the message should have been delivered
earlier and more forcefully.

I'm not sure I'd describe it as a *technology* failure. The passenger
has presented a set of cards to the reader, two of which have validity
for the journey. What do you expect to happen in those circumstances?

If the card furthest away from the reader pad is on the edge of the
acceptable range, it may or may not be read. So you might get a card
clash (neither card accepted - try again) or you might have the nearest
card used for the journey.

The failure is the lack of communication for several YEARS, by both TfL
and the banks. It took me some time to realise that the frequent
mis-read of my Oyster (Freedom Pass) at Tube stations was caused by the
RFID Barclaycard in the same wallet. That was long before RFID cards
had any validity on TfL services. Neither Barclaycard nor TfL had
bothered to warn me.

I think you contradicted your own claim here

If both cards are valid for the journey then you are right that the
technology may have difficulty deciding which one to charge (and certainly
wont know it has made a mistake if only one tries to "connect")

but cards that are not valid for the journey interfering with a card that
is, is a failure of the technology and ought to have been designed out at
the start

A properly designed system would instruct the cards to back-off for a
pseudo random period, then interrogate again. At that point it's much
more likely that only one would respond. Yes, I know it doesn't
currently work like that.

If the card furthest away from the reader pad is on the edge of the
acceptable range, it may or may not be read. So you might get a card
clash (neither card accepted - try again) or you might have the nearest
card used for the journey.


Another, lower-tech, option would be to have twin pads. One for Oyster
and another for contactless credit cards.

The failure is the lack of communication for several YEARS, by both TfL
and the banks. It took me some time to realise that the frequent
mis-read of my Oyster (Freedom Pass) at Tube stations was caused by the
RFID Barclaycard in the same wallet.


That can't be the case, because there's a combined Oyster/Contactless
Barclaycard which has worked perfectly well for years as an Oyster on an
Oyster-only pad.

That was long before RFID cards had any validity on TfL services.
Neither Barclaycard nor TfL had bothered to warn me.


Clashes have been known about for years - I used to have a door-entry
rfid card which I could not keep in my regular wallet as it interfered
with the Oyster.

Bus or tube?

The original article said (about buses):

"Almost 1,800 commuters have been given refunds totalling £11,000 after
Oyster readers charged the wrong card."

Then there's a recent "not-insignificant trial" which from the context
is on the tube. So the tube gates must be activated, and accepting
payments from people on that second trial (iirc the trial is only for
PAYG as season ticket holders didn't qualify).

The discussion I referred to (up there) mentioned gates.


That's right. The tube gates which have been recently activated for
contactless credit cards, and which must be contributing to the clashes.

What we don't know yet is how many of the tube gate clashes have
resulted in payments being deducted from a credit card, when the holder
also had an Oyster season. That's the mechanism that's over-charged
travellers at least £11,000 on the buses so far (plus we have to assume
that many such over-charges have gone un-noticed or un-complained
about).

I don't have exhaustive knowledge but I can't ever remember seeing
gates on buses in London recently.

None, as the gates are not able to charge live cards yet.


Not even the ones belonging to people on the tube-rollout pilot.

http://www.tfl.gov.uk/corporate/proj...mes/28751.aspx

One of my questions being, how do the gates know if a contactless card
presented to them at the moment belongs to a piloter or not?

I still don't understand how that tells it which of the two valid
cards to use.

On the theory that the fairly bad always triumphs over the good, I
expect the solution will be tin foil hat wallete with an external
pocket. My wallet has internal shielding on each card pocket so that
none of the cards in it are visible to external readers. It would not
be hard to make a modified version of such a wallet with one pocket
deliberately left unshielded, so you can use it to touch in without
removing the card from the wallet.

I understand all the reasons such an approach stinks, e.g., for people
who use the Oyster to get to work and a company ID to unlock the
office door, but you heard it here first.

If it got an answer from both (with a suitable separation), it could
decide to use the season ticket rather than the PAYG. Doesn't have to
take just the first one, especially just after it had detected a clash.

I suppose, but that still doesn't help in the many cases where there
is no clear reason to prefer one card over another. It seems a poor
use of funds to redo the gates when it will only help sometimes.

Like I said, people will get wallets that more or less solve the
problem.

There are now posters and signs around the transport network warning
against card clash, but I think the message should have been delivered
earlier and more forcefully.


That's another message from the newspaper article - the need for such
warnings, which are quite frankly a desperate attempt to cover up a
massive technology failure.


I'm not sure I'd describe it as a *technology* failure. The passenger
has presented a set of cards to the reader, two of which have validity
for the journey. What do you expect to happen in those circumstances?


A properly designed system would instruct the cards to back-off for a
pseudo random period, then interrogate again. At that point it's much
more likely that only one would respond. Yes, I know it doesn't
currently work like that.

If the card furthest away from the reader pad is on the edge of the
acceptable range, it may or may not be read. So you might get a card
clash (neither card accepted - try again) or you might have the nearest
card used for the journey.


Another, lower-tech, option would be to have twin pads. One for Oyster
and another for contactless credit cards.

I still don't understand how that tells it which of the two valid
cards to use.


If it got an answer from both (with a suitable separation), it could
decide to use the season ticket rather than the PAYG. Doesn't have to
take just the first one, especially just after it had detected a clash.


I suppose, but that still doesn't help in the many cases where there
is no clear reason to prefer one card over another. It seems a poor
use of funds to redo the gates when it will only help sometimes.

-------------------------------------------------------------------------

The gates get reprogrammed software frequently

However ISTM that the time taken to wait for the delay between the cards
re-transmitting is going to be a killer here - especially if you've three
(or four) cards

If I have two+ contactless credit cards then I really don't care which
of them TfL use, as long as they only use ones I've signed up to my
"capped account" of course.

I think they've vastly underestimated the number of people with more
than one 'rfid' card. In the near future there are likely to be lots of
people with at least one ITSO card, as well as one Credit Card, even if
they have decided to give up on Oyster.

Like I said, people will get wallets that more or less solve the
problem.


I've already had to do that (perhaps six years ago). How many different
wallets do they want people to have?

And remember that one of the USPs of Oyster was *not* needing to take it
out of your wallet to use.

"Just under one per cent of all Oyster and contactless journeys

Sorry, but 1% seems very high.

My experience of card clash is an error 94 & the gates don't open.

I didn't think that gates were enabled for contactless cards yet.


Given there's a not-insignificant trial running, I'd suggest they are.


I'd forgotten about the trial.

But it's very worrying that they are charging the credit cards of people
not signed up to the trial. That seems to me to be completely wrong, on
many levels (for example, it means anyone can join the 'trial' just by
proffering their card).


Neither card was charged, but the gates would not open.

Contactless card, oyster card & fredom pass all clash.

That's OK if you only have one rfid card you want to use frequently. The
problem with the proliferation of such cards is that this becomes
increasingly less likely.

Yes, that's your experience. Others (albeit only reported in the press
so far on buses) is that two cards can be recognised, and both "charged"
(although one might be a season, but that's still an overcharge
scenario).

I don't but I keep mine in a plastic Oyster wallet not with my credit cards. Even without the card clash issue I wouldn't start waving my main wallet around at a station gateline or getting on a bus.

Oh, wait, there is! Ask the nice man at the ticket office for a ticket

I've had a secondary wallet with all the "other" cards in for at least
as long as I've had an Oyster. But that doesn't cure the card-clash
between the "others".

For example, when I lived in Nottingham my main "other" card was a
pre-ITSO contactless bus card; but I still had an Oyster, and more
recently an ITSO card that in theory I could have loaded
Nottingham-London tickets onto (but the EMT trial had so may hiccups,
and still isn't mainstream afaict, that I never did manage to use it in
anger).

What it will be OK in a back pocket which you sit on as I do with my
paper season tickets? Otherwise putting two wallets in a front pocket is
not that convenient as you have to get both out to see which one to use.

I don't as a rule put things in back pockets because pickpockets
might be tempted. But in any case a thin season ticket wallet is so
obviously different from a thicker money wallet that I can't see such
confusion really occurring.

My experience (several times) is that got card clashes quite often:
unfortunately sometimes I got through the entry gate by following
someone just ahead, and then found an unresolved journey at the exit
gate (which then took me at least 30 mins on the phone to resolve).

I have learned from this to keep my Oyster card in a separate card
folder to all others, which is a real nuisance. But it seems the only
way.

As we accumulate more an more RFID cards (my credit card supplier has
refused to provide me with a non-RFID version) we will simply have to
keep a separate card holder for each and every card. Welcome to the
inconvenience of the pay-wave future.

That's a completely different issue. If you wait for the yellow light
before touching in, you'll avoid that scenario.

Do a Google image search for "trifold wallet". You can keep two RFID
cards in the outer flaps and all the other cards in the centre. When
touching in, you just fold out the flap with the Oyster in it. Simple.

Or just take out the desired card. When standing at a checkout this

You aren't at a checkout you are in the middle of maybe 20 people all pushing top get on the bus or at a barrier gate in the middle of the rush hour. The last thing you want is to hold up a wallet full of credit and debit cards where it can be grabbed let alone the fact that you will be getting jostled by a lot of impatient people.

For security and speed keep the Oyster card separate in the dedicated wallet provided.
