Yep cheque's are also still in use in the US. We're lightyears ahead of the rest of the world.
I used to use Eurocheques but man that feels like it was in the time of the arcade classics (which is not really so...)
Anyway, the French woman is dumb. You cannot do anything but transfer money TO an IBAN/BIC account. It is sad that the banks did such a bad job on informing their customers, but there''s a reason for that (they didn't like that they were forced the system in the first place, cost them money). I bet she doesn't even have internet banking...
I say forget it....
