Your question doesn't make much sense to me, but with what I've worked with _retailers_ do not send the electronic signature to the bank. It is for the retailers documents (ie to print on the receipt, or to store in a database with the transaction). In the case of a dispute they would then send the information.

Some payment network providers do provide electronic signature storage as a service for this purpose.
