发明名称 Message notification system for card users
摘要 Messaging service subscribers are automatically notified of newly arrived messages in their mailboxes when they initiate a transaction, such as a calling card (or credit card) call, or a withdrawal at an Automated Teller Machine (ATM). The mail arrival notification message is delivered to the subscriber as part of the validation process for the credit/debit or calling card number.
