In December 1985 Minitel users made more than 22 million calls, up 400% in one year. In 1994 they made 1,913 million Minitel calls, used the system for 110 million hours, and spent 6.6 billion francs. In 2005, there were 351 million calls for 18.5 million hours of connection, generating €206 million of revenue, of which €145 million were redistributed to 2,000 service providers (these numbers were declining at around 30% per year). There were still six million terminals owned by France Télécom, which had been left with their users in order to avoid recycling problems. The main uses were banking and financial services, which benefit from Minitel's security features, and access to professional databases. France Télécom mentions, as an example of usage, that 12 million updates to personal "carte vitale" health-care cards were made through Minitel.
