e-isolement is a business application which aims to simplify and improve the isolation controls of technical centres done by SNCF agents. The aim is also to secure the traceability and the synchronisation of the information between the different sensors and databases. NFC-Interactive offers a software solution available on tablets and smartphones combined with memory holding RFID tags. Data are also stored in the smartphones before being synchronised once the agent is back online (3G,4G, Wi-fi).
