UML activity diagram - Payment process

"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 Data flow diagram (DFD) example "Payment for goods using UPS code scanner" shows data flow in process of payment for goods in the shop using the MaxiCode scanner.
"MaxiCode is a public domain, machine-readable symbol system originally created and used by United Parcel Service. Suitable for tracking and managing the shipment of packages, it resembles a barcode, but uses dots arranged in a hexagonal grid instead of bars. MaxiCode has been standardised under ISO/ IEC 16023.
A MaxiCode symbol (internally called "Bird's Eye", "Target", "dense code", or "UPS code") appears as a 1 inch square, with a bullseye in the middle, surrounded by a pattern of hexagonal dots. It can store about 93 characters of information, and up to 8 MaxiCode symbols can be chained together to convey more data. The centered symmetrical bullseye is useful in automatic symbol location regardless of orientation, and it allows MaxiCode symbols to be scanned even on a package traveling rapidly." [MaxiCode.
