To Whom It May Concern

Based on stringent vendor selection criteria, Cosmic Commercial Services Ltd.(CCSL) was selected among several famous system providers to install the Northern Computers’ Assess Control System in my centre to provide total security measures for restricted areas.

In order to provide the integrated System Control and Transaction Monitoring in my office, a File Sever and a client station were installed in two respective locations. Since the System installation completion, CSSL has shown her excellent engineering competence, reliable system design and successful follow-up actions to suit my request. Accordingly, I highly recommend to any company which needs a highly reliable security system. If you are interested to see this system in operation, you are cordially invited to visit my centre for a system demonstration.

Should you have any queries, please do not hesitate to contact the undersigned.

Yours sincerely,



Director of EPA Centre
