Calypso® is an open, secure standard for ticketing always with a focus on flexible and long-term deployable products. It is used in more than 25 countries and over 170 cities worldwide and was developed by transport companies and authorities for transport companies and authorities to ensure long-term usability and sustainability.

nagels is a member of the Calypso® Network Association (CNA) and benefits from the association's continuous support. We are one of more than 50 manufacturers who promote innovation and create products that are available and usable by all.

At nagels, we offer two types of Calypso® tickets - Calypso® Light and Basic. Both tickets comply with all international standards, are independently certified, and are designed to use the same data model and occupy only a small volume of data in the terminal software for managing ticket transactions.
