Calling Cards - The Technology used During the Year

Calling a local or international calling cards is just about the most common phenomenon today. However, if you know what technology goes into these calling cards? The two main technologies used in the so-called cards, stored value and remote memory, have been used for prepaid phone cards, which are popularly used phone card over the world. SIDA, the European telecommunications company made its first calling card system of the mid-1970s, but it will take another decade, the phone card users to reach the U.S. and around the world.

The pre-stored value cards from the first phone calling cards with a magnetic stripe encoded information, similar to the main card or ATM technology. A few years later came the optical storage technology, which was more complex than previously used for the magnetic encoding. Optical phone cards had physical readers, such as lines or ports, card reader search for the balance of information cards. Optical phone cards are widely used by many users around the world. Optical phone cards, a relatively simple technology, so the drawback that they can easily be hacked. Due to these security issues optical calling card has been slowly phased out of countries around the world.

Over the next decade, new technology was to find a phone card system, which was the chip technology. For the first time in Germany, Deutsche Bundespost in 1986, this chip stored value calling cards, quickly became the norm when it came to the phone card technology in the next few decades. While the original problem was easy to scratch off the card point of the programming voltage is caused by the breach of security, then the technology was much more reliable. With this basic chip card technology, today the use of calling cards and chips are not easily hackable,,, to secure coding techniques.

Other technologies used in isolation from the stored value system is a remote storage system. This includes a central database that provides information on the balance sheet, which records a card access number. The company launched its first line of remote memory calling card in the U.S. in 1980. These phone cards can usually be used from any phone with tone dialing mode option. It really was to increase the users, because it was with the phone around so that the necessary special card reader phone card. The only drawback to this type of card confesses to enter many digits as you can actually call. International calling cards and remote memory is required before the call can be connected, but that does not call for an error, the caller to collect three different numbers. This process was really very difficult for consumers, and it was a major disadvantage of such a calling card.

Today, mobile phone or landline user can enjoy the many benefits of their calling cards. Depending on the telecommunications service provider of such calling cards, you can choose in which networks to be applied so as to provide discounted rates, as well as the best insurance.
