UML Activity Diagram. Design Elements

"A payment is the transfer of an item of value from one party (such as a person or company) to another in exchange for the provision of goods, services or both, or to fulfill a legal obligation. ...
Payment methods.
There are two types of payment methods; exchanging and provisioning. Exchanging is to change coin, money and banknote in terms of the price. Provisioning is to transfer money from one account to another. In this method, a third party must be involved. Credit card, debit card, Cheques, money transfers, and recurring cash or ACH (Automated Clearing House) disbursements are all electronic payments methods. Electronic payments technologies are magnetic stripe card, smartcard, contactless card and mobile handset. Mobile handset based payments are called mobile payments." [Payment. Wikipedia]
The UML activity diagram example "Payment process" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.

The vector stencils library "Bank UML activity diagram" contains 32 shapes of UML activity diagram.
Use it for object-oriented modeling of your bank information system.
"Activity diagrams are constructed from a limited number of shapes, connected with arrows. The most important shape types:
* rounded rectangles represent actions;
* diamonds represent decisions;
* bars represent the start (split) or end (join) of concurrent activities;
* a black circle represents the start (initial state) of the workflow;
* an encircled black circle represents the end (final state).
Arrows run from the start towards the end and represent the order in which activities happen.
Activity diagrams may be regarded as a form of flowchart. Typical flowchart techniques lack constructs for expressing concurrency. However, the join and split symbols in activity diagrams only resolve this for simple cases; the meaning of the model is not clear when they are arbitrarily combined with decisions or loops.
While in UML 1.x, activity diagrams were a specialized form of state diagrams, in UML 2.x, the activity diagrams were reformalized to be based on Petri net-like semantics, increasing the scope of situations that can be modeled using activity diagrams. These changes cause many UML 1.x activity diagrams to be interpreted differently in UML 2.x." [Activity diagram. Wikipedia]
This example of UML activity diagram symbols for the ConceptDraw PRO diagramming and vector drawing software is included in the ATM UML Diagrams solution from the Software Development area of ConceptDraw Solution Park.
