Summary/Description of Process:
This Diagram shows the process in which a user
interacts with a terminal so that they can exchange
their hard currency (cash) into another form of hard
currency (for example changing Czech Crowns to
Euros).
The process is simple, initiate the system, choose
desired currency conversion, insert your cash and
choose desired output currency, scan your ID and
after validation collect your cash.

Task types are missing -1
When the process is modeled in the pool, then message flow has to enter activity or event
not just the pool (-1)
Missing name of the outcome (End event) -1
This is rule event, displaying the message to customer is rather activity.
The process is a little bit weird - it is very passive
(it assumes a lot of messages will come from outside).
Improve alignmet of sequence flow.
