Credit Card Processing System UML Diagram

"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 If the currency being withdrawn from the ATM is different from that which the bank account is denominated in (e.g.: Withdrawing Japanese yen from a bank account containing US dollars), the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]

"IVR systems are typically intended to service high call volumes, reduce cost and improve the customer experience. Examples of typical IVR applications are telephone banking, televoting, and credit card services. Companies also use IVR services to extend their business hours to 24/ 7 operation. The use of IVR and voice automation allows callers' queries to be resolved without the need for queueing and incurring the cost of a live agent. If callers do not find the information they need or require further assistance, their calls are often transferred to an agent. This makes for a more efficient system in which agents have more time to deal with complex interactions. The agents do not deal with basic inquiries that require yes/ no responses or obtaining customer details. ...
