Acsys has designed and successfully deployed a solution called the CGS (Code Generating System) which allows control centers (such as a telco or towerco’s NOC) to give users with programmed keys access to any site, anytime, anywhere by issuing a single-usage time-limited code that is issued by the software. The user needs to contact the control center by phone or SMS to get the real-time code which in turn alerts the control center that someone is accessing the site. The advantage of the Acsys CGS solution is that any phone can be used, making its application universal.
