Notetrack(tm) system for monitoring movement of notebook/laptop computers from premises
A hardware and software system for managing the passage of notebook/laptop computers past an access point in a Small Business.
Laptop and notebook computers are expensive items, often containing important confidential data. They are often stolen from business premises as they are easy to disconnect from their environment and easy to hide. Some businesses require many staff to take their laptops out of the office regularly for the execution of their duties.
This system will allow the passage of notebook computers past a security point provided that the carrier of the computer has a matching ID card which has been linked to that computer in a database. Non-matching IDs or computers that are not associated to a personal ID card will cause an alarm to be shown at the security checkpoint.
The system comprises of transponder tags for attaching securely to the laptops, ID cards that are carried by the users, a long range fixed UHF RFID reader for monitoring the access point, a software package running on a computer at the guard station, and a software package running on a database administrator's personal computer.
The system uses the long range capabilities of the reader and the transponders to allow identities of items to be read at a distance. This means that when a laptop computer and an ID on a person get within up to 5 meters of the access point, the ID cards can be read by the long range reader and passed onto the computer software for processing.
Transponders for laptops
With this technology, the passage of the computer can be detected when it passes any reader station, which will usually be situated at the access points to the building.
Because computer systems have very high clock frequencies which generate radio interference for other users, they are shielded from the outside world by being placed in cases that contain their radio energy. This case stops any radio signals passing into the laptop or leaving the inside of the laptop. As a result, the RFID tag needs to be mounted on the outside of the laptop to interact with local readers via radio signals.
The Trolley Scan RFID transponder is a rubber based tag that is glued onto the outside of the computer case. The tag can be attached anywhere to the outside of the computer case. It will be detected when it passes the reader even if it is screened from direct radio path with the reader by the computer itself. The rubber tag has a high resistance to chemicals and solvents. The glue is very strong and will prevent the tag being removed. It is a passive tag with a very long expected lifetime.
The transponders are passive (do not have a battery) and have a lifetime of more than ten years.
Asset monitoring software
The software has a database of notebooks, a database of users, and a database that links the users to the notebooks. When receiving ID codes from the reader, the software in the guard point computer checks that any code from a notebook computer has the matching code from the user within a preset time, as detailed in the linking database. Should this match be present, the passage of the notebook and the user is recorded in a log file. Should no match occur within the predefined time, an alarm condition is displayed on the guard point computer and details of the notebook computer are displayed as well as the details of the registered user and their contact details are shown. Many notebooks can be linked to a single authorised user, and many users can be linked to a single notebook.
The Notetrack management program is a customised program that allows the user to set up the system for all measurements via drop down menus. The system generates reports that can be viewed and printed from any WWW browser to provide a paper trail.
All databases are stored in common type formats, letting programs like Excel spreadsheets import/export the master database for massaging and data capture should that be necessary.
