I've been using an "Orange Cash" prepay card but I got an email
yesterday saying that EE are bailing out and I'm going to be
transferred to a different issuer.

Optimum by Prepay Technologies

It's not clear if the replacement is also contactless, so I've
queried this by email.

12 days later they've got back to me with a one sentence reply of "yes
it will be contactless".

It now occurs to me that I asked the wrong question, and should have
been enquiring about whether such a card, if contactless, was accepted
by TfL.

I'll continue trying to pull these particular teeth.

So I asked the question, and six weeks later... no response.

The Optimum card itself arrived yesterday (2nd October) so only a day
later than the Orange Cash card went to meet its maker. The good news
is they did transfer the balance across, and it's contactless.

I suppose I'll have to try it out next time I'm in London to see if TfL
accept it.

They do.
