DSL Systems has developed a method to automatically log users in to a workstation using wearable RFID tags, typically on the wrist. Each workstation is installed with a RFID reader plugged in to the USB port which can have a range of about 1m. Software on each workstation continuously scans for tags in range and will automatically log-in a user with a recognised tag. The user will be automatically logged out when the tag has been out of range for a short time. User log-in provides system security by restricting access to the menu system. It also provides accountability by auditing all changes and operations by the user.
