Recently my Freedom Pass has failed at some Oyster Readers (usually Underground ones)with an error 94.

The only thing that has changed is that I now have in my wallet a proximity debit card.

Would this cause problems?

Yes, because the readers are being modified to accept these as a
pseudo Oyster.

I think presenting two different cards always caused a problem. It's the
Achilles Heel of virtually every RFID card implementation.

On the other hand, my dual "Paywave and Oyster" Barclaycard works fine,
which means perhaps it's got some clever avoidance technology.

It shouldn't be too hard a problem to solve - ethernet has managed to do
collision detection since the 80s. I guess it depends on how smart they
want to make the hardware in the card.

My Oyster card will not read if I have a PATH Smartlink card next to it.
However, at least four years ago when I last used it, the Smartlink card
will work quite happily on the readers on the PATH turnstiles when next to
an Oyster card, so it can't be too difficult to make it ignore a 'foreign'
card not valid on that system. Of course it's slightly more difficult when
two valid cards, say an Oyster and a VISA debit card can both be seen.

Actually, there's no reason for it to be symmetrical. What if, when
energised, the Smartlink card produces a much stronger signal than an
Oyster so that when used on PATH it swamps the Oyster signal and is
recognised, and on a TfL gate it swamps the Oyster signal and the gate
can't see the Oyster.

In my experience even a first generation chip and pin card could interfere with any variant of an Oyster card being read. I always carried mine in a separate wallet and now use a third wallet for my ENCTS card.

It's nice to see how easy these contactless cards make our lives!

Don't ever make the mistake of thinking this is done for the passengers
benefit - just like Oyster its done entirely for TfLs benefit (a paper
travelcard was just as simple to use as an Oyster card but you didn't need a
5 quid deposit first). Soon they'll be able to suck money direct out of
peoples bank accounts and no doubt plenty of mugs are already lined up to
help them do it.

There's even a poster about this on some bus stops, basically;

Oyster and other cards are bad medicine and sometimes the reader will ignore
the Freedom pass and charge your card.

I always keep my Freedom pass in its own wallet.
