Doboy Inc. offers key fob technology to secure access to the control panel of packaging lines. The technology allows for numerous levels of security such that each user has an individualized level of access to the controls. Access levels for displays, data entry, control, monitoring and system operations can be configured on a machine-by-machine basis, customized to the requirements of different production environments. The technology is implemented using a fob format that can be carried on a key ring. The fob is touched to a magnetic reader to gain access to the control panel interface.
