A telephone card, calling card or phone card for short is a small card, usually resembling a credit card, used to pay for telephone services. Such cards can either employ prepaid credit system or credit card style system of credit. The exact system for payment, and the way in which the card is used to place a telephone call, depend on the overall telecommunication system. Currently, the most common types of telephone cards involve pre-paid credit in which the card is purchased with a specific balance, from which the cost of calls made is deducted. Pre-paid phone cards are disposable. When the balance is exhausted you simply buy a new card. Cards purchased can often be refilled. The other main type of card involves a card with a special PIN printed on it that allows one to charge calls to a land-line telephone account.
A stored value card that allow the user to access pre-paid long distance. The long distance is generally accessed via a PIN number (stored value ...). A smart card that stores the key identifying a mobile phone subscriber within a specific country; and the international SIM card, which allows smart card holders to send and receive calls from around the world on their cellular phones with one prepaid card. The international prepaid SIM card gives cardholders the convenience of global roaming and one phone number. Both types are also available in a non prepaid variety; here, phone calls are billed to clients in much the same way that a regular telephone service provider bills clients placing long-distance telephone calls.
In recent times, calling card service providers have gone one step ahead in reducing the costs and increasing convenience by introducing calling accounts. Calling accounts eliminate the need for printing of a physical card; accounts are available only in electronic form. Calling accounts can be purchased over the Internet using credit cards and are instantly delivered to the customer via e-mail. This e-mail contains the PIN and instructions for using the service.
