Pay Fee With Credit Card
Brief Description
This use case occurs when a new subscriber wants to pay their annual
subscription fee by specifying a credit card number and PIN. This may also occur
when an existing subscriber wants to renew (see alternate flow 1)
Flow of Events
Basic Flow

Subscriber selects "pay fee with credit card"
System prompts subscriber for credit card number, expiration date, and
(optionally) PIN
System sends credit card info to external system for charge validation and
application
Upon receipt of validation, system updates subscriber record to indicate
new expiration date

Alternate Flows
Subscriber renews subscription
When this occurs, the flow runs as follows:

Subscriber selects "pay fee with credit card"
System displays current credit card information
User either accepts information as is or updates appropriately
System sends credit card info to external system for charge validation and
application
Upon receipt of validation, system updates subscriber record to indicate
new expiration date

Invalid credit card information
If the information provided by the subscriber is not validated by the
external system, an error message will be displayed and the subscriber record
will NOT be updated (so that the last steps in the above flows will not be
executed).
