Indra will work in cooperation with its domestic partner Keltron on the project which will replace the existing 20-year-old ticketing system with a new one that can be used both manually and automatically.
Indra's system is equipped with contactless technology that enables passengers to use multi-journey electronic cards as well as tokens for a single trip. The system validates tickets using a radio frequency by the means of contactless access control systems and will be able to co-exist with the new east - west metro line which is currently under construction.
