UML activity diagram - Cash withdrawal from ATM

"An automated teller machine or automatic teller machine" (ATM) (American, Australian, Singaporean, Indian, and Hiberno-English), also known as an automated banking machine (ABM) (Canadian English), cash machine, cashpoint, cashline or hole in the wall (British, South African, and Sri Lankan English), is an electronic telecommunications device that enables the clients of a financial institution to perform financial transactions without the need for a cashier, human clerk or bank teller.
On most modern ATMs, the customer is identified by inserting a plastic ATM card with a magnetic stripe or a plastic smart card with a chip that contains a unique card number and some security information such as an expiration date or CVVC (CVV). Authentication is provided by the customer entering a personal identification number (PIN). The newest ATM at Royal Bank of Scotland allows customers to withdraw cash up to £100 without a card by inputting a six-digit code requested through their smartphones.
Using an ATM, customers can access their bank accounts in order to make cash withdrawals, get debit card cash advances, and check their account balances as well as purchase pre-paid mobile phone credit. If the currency being withdrawn from the ATM is different from that which the bank account is denominated in (e.g.: Withdrawing Japanese yen from a bank account containing US dollars), the money will be converted at an official wholesale exchange rate. Thus, ATMs often provide one of the best possible official exchange rates for foreign travellers, and are also widely used for this purpose." [Automated teller machine. Wikipedia]

"Bank accounts may have a positive, or credit balance, where the bank owes money to the customer; or a negative, or debit balance, where the customer owes the bank money.
Broadly, accounts opened with the purpose of holding credit balances are referred to as deposit accounts; whilst accounts opened with the purpose of holding debit balances are referred to as loan accounts. Some accounts can switch between credit and debit balances.
Some accounts are categorized by the function rather than nature of the balance they hold, such as savings account.
All banks have their own names for the various accounts which they open for customers." [Bank account. Wikipedia]
