Especially for the section of the general requirements latest technology trends should be integrated. It should be possible to use highest security standards [18], e.g., by identification with a radio frequency identification (RFID) and monthly new activation of RFID by a user transmit-ted transacting number (TAN) [19]. The idea is that labora-tory personal would log on to thin clients (only operating system) by using RFID chips. To log on to LIS still a per-sonal login and password should be necessary. To ensure that only authorized personal can logon to the clients, a regularly activation is necessary. The benefit here would be that several laboratory staff could use the same clients but each user would operate within his/her own profile and switching between different user profiles would be rapid.
