So surely what you have is a completely separate system that has
exactly one interface to it, that is signaled to provide a
transaction number and that only ever returns such a transaction
number to the "online" system, and that is very tightly secured,
right?

It is possible to make trade-offs in an intelligent manner, for sure,
but you sure as heck don't want that kind of data stored online with
simple reversible encryption.
