To Adapter or Not to Adapter?

| Hi,
I am faced with an interesting problem, of which I'd like to pose the
question to all. This one is defiantly an advanced question.
I need to design an interface to an external system for credit card
processing batches.
I receive a batch request for payment, and need to send back a correlated
response batch.
The external payment system only takes single transactions, at a time, not a
batch.
The added complication is that I have to look up an encrypted credit card
and decrypt it as the last moment, due to the sensitive nature, and I do not
want to have the card exposed anywhere in BizTalk it is encrypted until the
last moment.
I am looking at an adapter to provide this, however is it feasible to do
this much logic in an adapter?
Has anyone built a similar interface?
Is there a better way?
Regards,
Paul.

| Hi,
Here's my thoghts about your scenario.
I'm pretty sure I'd do all the batching/debatchin in an orchestration. You
have to be aware of the "zombie-problem", but I think you should be able to
do a design, that avoids them.
The decryption of the credit card details I'd do in a pipeline component.
Use the "encryption" stage - that way the decryption will be done just before
the message is handed to the adapter.
I'f you'd do all the work in an adapter, I can't see why you would use
BizTalk at all unless you have to do som workflow or advanced mapping before
the call to the adapter.
