Puerto Rico is the smallest island of the Greater Antilles, an unincorporated territory of the United States of America, located in the north-east of the Caribbean Sea between the Dominican Republic and the Virgin Islands, for which a legislative process has been launched, that could transform the island into the 51st state of the Union. Only remote memory cards were sold to the public, starting with the first, issued in 1995 by Telecom Global Communications, with a circulation of 1,100 copies and a face value of 10 US dollars. In reality, however, the honor of being the first phone card used in Puerto Rico goes to a GPT issue with 2CCMA code: it was produced in 1,200 copies at a Convention of the Caribbean Hotel Association (CHA) held in S. Juan of Puerto Rico in June 1991. A single telephone was prepared for the delegates and this card was distributed to them. CHARMS stands for “Caribbean Hotel Association Room Management System” and is a joint-venture between CHA and Cable & Wireless.
