Types of Cards Used In Ireland.
Over the last 11 years callcards have proven to be quite successful, and have proven themselves as a great alternative from having to worry about the hassle of carrying around lose change in order to make a phone call. So how did callcards come about. Well before Telecom Eireann jumped into the idea of coin less phone calls, they conducted a number of trials in Dublin, Limerick and Galway and their surrounding areas to see if they would be successful...
At the end of these three trials Telecom adopted a totally different system, the smart card which was introduced into Ireland in the early 90's. However what did all these cards look like, and who developed them. Well check them all out in this easy to follow chart.
Dublin Plessey Trial Cards. | ||||||
Developed by G.P.T. Telecom. The Dublin
Plessey cards were of standard I.S.O. magnetic cards and are manufactured from several
layers of "PVC". Once the cards have been printed, the back is fitted with
a magnetic medium and are encoded, which is used to store any units remaining in the card. After the card has been encoded the card is laminated with a sheet of transparent plastic on both sides. This stores the printed image and the data embedded into the card. Finally the notch is cut into the card so that blind people could insert the card the right way round.
The cards were available in 5, 10, 20, 50 and 100 unit denominations.

Limerick "Autelca Trial Cards." | ||||||
The Autelca trial began on the 9th of
February 1989. These wafer thin cards were both flimsy and reportedly un-safe and easy to
crack... Developed by Autelca the Limerick trial cards are of the same design to cards used throughout the world. A total number of 31 phone-booths were installed throughout various part's of Limerick city and county for this trial. Telecom also used the Autelca trial as means to sponsor the I.M.I. conference of 1989 by releasing two cards(20 and 50 unit card) to mark their involved with the institute. The cards were available in 5, 10, 20, 50 and 100 unit denominations.

Galway "Landis & Gyr Trial Cards." |
||||||
The Galway Landis & Gyr trial began on
the 11 November 1989, but only lasted a very short time. As a result it is quite rare to
find a used Galway card. These cards are the most secure of the three trials. How the card works is quite simple. An infra-red beam is passed along the track at the top of the card (usually located on the front of card). This creates a unique fingerprint. Once the card has been printed the optical track is embedded into the structure of the card and then covered with a thermo graphic layer. There was a total of nine Landis & Gyr Phone-Booths installed throughout Galway city all of which are reported to have been destroyed after the trial ended.
Card No: 1009 |

The Smart Card |
||||||
The smart-card was developed by Roland Moreno in 1976.
Telecom Eireann adopted the smart-card system in 1990 after the three trials had brought
back it's own number of advantages and disadvantages. Telecom Eireann realized
that if
people were to accept Callcards then they would have to of light weight, of ease to use
and to be readily available in most shops throughout the country. They also realized at an early stage of each of the three trials that, certain individuals such as business men or tourists who traveled to different parts of the country were annoyed to find that they couldn't use a card that they had purchased in Limerick in Dublin due to the different trials taking place and vice versa.
Hence the introduction of the Smart-Card, a light but versatile card no bigger or heavier than a standard credit card. The smart card was more expensive to develop but competition in the development was widespread and Telecom Eireann realized their early potential and even foreseen further enhancements to Callcards way back in the early 90's when they released the Dash card in Dublin. Today they trying out a similar trial with the Visa Cash Card Trial in Ennis in Co. Clare. Most chip cards contain EPROM chips, which means that once the card has been programmed it cannot be recharged.

Remote Memory Cards: However as time has moved on and the cost of international calls has dropped dramatically the introduction of Remote memory cards was inevitable. When the first widely used card was introduced in 1994 nobody ever bothered much with them and many collectors seemed to pass them over. Now eight years on, and hundreds of different remote memory card companies later one may wonder are these the only cards we are ever going to find for our collections, as callcard releases have faded away to their cheaper counterpart and become impossible to obtain. But to be truthful some remote memory card releases have been carefully designed to attract collectors and customers alike and are proving to be hard to obtain themselves. So keep your eyes open as you may just find a remote memory card that may take to your liking, you have been warned.
