\caption{Deposit interactions between customer, Taler exchange (payment
|
||
|
|
service provider) and the AML staff. The process can be
|
||
|
|
triggered by various {\em actions} described in Chapter~\ref{chap:triggers}.
|
||
|
|
AML staff interactions are cryptographically secured and
|
||
|
|
decisions and the provided reasoning are archived by the exchange.
|
||
|
|
AML staff may interact with the customer (out-of-band)
|
||
|
|
in its decision process.
