Calling card replenishment system
摘要:
A method and system of real-time replenishment and electronic confirmation of sale, such as a SMS text message, to a consumer responsive to purchase or referral of long distance calling minutes, including real-time replenishment of the customer's account, and seamless, pin-less use of the purchased long-distance from the user's chosen phone(s). A computer based server receives a phone number, monetary amount, and an indication of whether an increase or decrease to the balance is requested. Phone number is then compared with a stored list of registered phone numbers having a unique pin and a balance amount. The balance is increased or decreased by desired amount if comparison results in a match. If comparison does not result in a match a new pin is created associating the phone with the balance amount. A message is then sent containing an access number for use in pre-paid long distance calling.
