Second, IC card access control system composed of aging 
 Aging access control IC card access control system is mainly one machine, collector (non-networked), card reader, card, software and other several parts. 
 Third, IC card access control system features time 
 1. Safe 
 Aging access control, time-bound, the average time limit for networked access control system is downloaded through the network communication, if the network blocked, poor time to download information to a security risk. The access control system relative to the normal time-based access control system has time to set permissions, users can set the holder on demand any valid time period (such as: authorization to someone in a certain time period, and only you can access at this time .) Non-effective time period can not access. 
 2. Stability 
 Access time is the authority and effectiveness of the card write IC card sector, the clothes do not need to rely on nature through the network to control, when one controller fails, will not bring disaster to the entire system. Fully reflects the centralized management, distributed control design, risk reduction, increased reliability. As low dependence on the network, the natural increase system stability. 
 3. Easy installation and low cost 
 Aging can not access network to achieve network access control functionality eliminates the need for the project installation costs, simple construction.
