Calypso (electronic ticketing system)

<h2 id="history">History</h2>
<p>Calypso was born in 1993 from a partnership between the Paris transit operator <a href="/facts/R%C3%A9gie_Autonome_des_Transports_Parisiens/5JkKtUly">RATP</a> and <i>Innovatron</i>, a company owned by the French smartcard inventor, <a href="/facts/Roland_Moreno/UJ7yNPup">Roland Moreno</a>. The key features of the scheme were patented by <i>Innovatron</i>. Most European transit operators from Belgium, Germany, France, Italy and Portugal eventually joined the group in the following years. The first use of the technology was in 1996.
</p><p>In the same time, the international standard <a href="/facts/ISO/IEC_14443/oUq2AL5f">ISO/IEC 14443</a> for <a href="/facts/Contactless_smart_card/Uf0Khy7R">contactless smart cards</a> was being designed, and the actors of Calypso strongly lobbied to have their technology included in the standard, but Innovatron's patents—and the price of the related royalties—were not compliant with ISO's policy. Therefore, despite their closeness, there are few significant differences between Calypso's historical contactless protocol and ISO/IEC 14443 Type B international standard.
</p><p>The European standard for ticketing data (EN1545) has also been contributed by the actors of Calypso.
</p><p>After a few years of trials, the system has been generalised in the early 2000s in major European cities such as Strasbourg, Paris, Venice, Lisbon, later followed by Turin, Porto, Marseille, Lyon, and many smaller cities. Calypso is extended now in other countries such as Belgium, Israel, Canada, Mexico, Colombia, etc.<a class="footnote-ref" id="fnref:1" href="#fn:1"><sup>1</sup></a>

<h2 id="technical-aspects">Technical aspects</h2>
<p>Calypso is based on two main technologies:
</p>
<ul><li>The microprocessor <a href="/facts/Smartcard/K7b9lowS">smartcard</a>, widely used in many monetary transactions;</li>
<li>The <a href="/facts/Contactless_smart_card/Uf0Khy7R">contactless</a> interface (improperly called <a href="/facts/RFID/4CnmIV2b">RFID</a>) ensuring both remote powering and communication between the reader and the card.</li></ul>
<p>A Calypso card, whatever its form (card, watch, mobile phone or other <a href="/facts/Near_Field_Communication/awqd3Ea8">NFC</a> object, etc.) has a <a href="/facts/Microprocessor/Fx9CaQht">microprocessor</a> which contains all the information related to its owner rights for the application, and which implements the Calypso authentication scheme for security. This makes a difference with other e-ticketing system, such as London's <a href="/facts/Oyster_card/u3M4eMIA">Oyster card</a>, where the card is only a memory chip with no processing capabilities.
</p>
<h2 id="calypso-networks-association">Calypso Networks Association</h2>
<p>A non-for-profit association, <i>Calypso Networks Association</i> (CNA), has been created to regroup the transit network operators using Calypso, and the suppliers of Calypso compliant equipment. This association promotes the standard to new operators and manufacturers, defines the certification policy to guarantee the compatibility of all current and future products, and governs the evolution of the standard. This technical job is actually performed mainly by a subcontractor, <i>Spirtech</i>.
