Informer Systems has launched Sentrinet access control software, to allow users to log on to a Novell or Windows NT network with their name and fingerprint rather than a password. The company claims elimination of password management from the IT systems support workload can save up to £150 per user a year. Fingerprint use speeds up log-on and improves security, it says. Sentrinet runs on Novell 4.11 or 5.00 and NT 4.0 and costs from £40.
