Information: - Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection. - Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. Chilean territory includes the Pacific islands of Juan Fernandez, Salas y Gomez, Desventuradas, and Easter Island in Oceania. Chile also claims about of Antarctica, although all claims are suspended under the Antarctic Treaty. - MIFARE is the NXP Semiconductors-owned trademark of a series of chips widely used in contactless smart cards and proximity cards. - Latin America is a group of countries and dependencies in the Americas where Romance languages are predominant. The term originated in 19th century France as "Amerique latine" to consider French-speaking territories in the Americas (Haiti, French Guiana, Martinique, Guadeloupe, Saint Martin, Saint Barthelemy) along with the larger group of countries where Spanish and Portuguese languages prevailed. It is therefore broader than the terms Ibero-America or Hispanic Americathough it usually excludes French Canada and modern French Louisiana. - The megadiverse countries are a group of countries that harbor the majority of Earth's species and high numbers of endemic species. Conservation International identified 17 megadiverse countries in 1998. Many of them are located in, or partially in, tropical or subtropical regions. - A proximity card or prox card is a "contactless" smart card which can be read without inserting it into a reader device, as required by earlier magnetic stripe cards such as credit cards and "contact" type smart cards. The proximity cards are part of the contactless card technologies. Held near an electronic reader for a moment they enable the identification of an encoded number. The reader usually produces a beep or other sound to indicate the card has been read. Proximity cards typically have a read range up to 50cm (< 15 inches) which is the main difference with contactless smartcard with 2 to 10cm (1 to 3 inches) . The card can often be left in a wallet or purse, and read by simply holding the wallet or purse near the reader. The term "proximity card" refers to the older 125kHz devices as distinct to the newer 13.56MHz contactless smartcards. - NXP Semiconductors N.V. is a Dutch global semiconductor manufacturer headquartered in Eindhoven, Netherlands. The company employs approximately 45,000 people in more than 35 countries, including 11,200 engineers in 23 countries. NXP reported revenue of $6.1 billion in 2015, including one month of revenue contribution from recently merged Freescale Semiconductor. - A smart card, chip card, or integrated circuit card (ICC) is any pocket-sized card that has embedded integrated circuits. Smart cards are made of plastic, generally polyvinyl chloride, but sometimes polyethylene terephthalate based polyesters, acrylonitrile butadiene styrene or polycarbonate. Since April 2009, a Japanese company has manufactured reusable financial smart cards made from paper. - South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil). - Ecuador, officially the Republic of Ecuador (which literally translates as "Republic of the Equator"), is a representative democratic republic in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean to the west. Ecuador also includes the Galapagos Islands in the Pacific, about west of the mainland. - The RioCard ( Bilhete Unico ) is a smartcard system used in the transport system of Rio de Janeiro state , Brazil . The card is contactless and uses MIFARE technology . It is a form of electronic payment produced and distributed by the Fetranspor company , in cooperation with Itau bank . Its installation was seen as strengthening Brazil 's connection with the Open Standard for Public Transport ( OSPT ) Alliance . In October 2013 , Rio de Janeiro launched a trial run for this ticket to be run on smartphones , using near field communication ( NFC ) technology . Around 200 users of the ticket on buses , trains and ferries were selected for the trial , which involves putting a Motorola Razr D3 within a few inches of the reader terminal . Users can then check the balance of their card . Soon , one will be able to prepay fares by using one 's phone . - A contactless smart card is a contactless 13.56-MHz credential whose dimensions are credit-card size. Its embedded integrated circuits can store and sometimes process data and communicate with a terminal via radio waves. There are two broad categories of contactless smart cards. Memory cards contain non-volatile memory storage components, and perhaps some specific security logic. Contactless smart cards do contain read-only RFID called CSN (Card Serial Number) or UID, and a re-writeable smart card microchip that can be transcribed via radio waves. - Bilhete Unico ("Unified Ticket") is the name of the Sao Paulo transportation contactless smart card system for fare control. What is the relationship between 'riocard' and 'proximity card'?
