Oyster was meant to

believe its a similar situation at SWT.

They have changed something, last year when in London, I discovered the
LU readers were responding to my Singapore CEPAS card, where as the
Oyster readers on the buses were ignoring it.

In fact they were responding to the CEPAS card while it was still in my
pocket and I was holding the Oyster in my hand next to the gate reader.

Experiments with the ticket machines at Earls Court revealed the ticket
machine would respond to the Singapore CEPAS card at 30-40cm where as the
Oyster had to be with in 10cm. It's actually a surprise the security
people didn't come over and ask what I was doing :-)

(Every time the Singapore card got anywhere near an LU Oyster terminal
it would respond with 'multiple cards presented', even if the proper
Oyster card was kept well away)

At a guess the Oyster terminal was interacting with the card and
discovering it had multiple 'products' loaded, generating the multiple
card error before noticing that none of the products were usable by it
anyway. (The Singapore CEPAS cards are used to pay road tolls via
hardware installed in each car as well as transit fares, so I assume have
multiple 'products' loaded).
