SYSTEM AND METHOD FOR MAINTENANCE OF PUBLIC SECURITY AND EXIT AND ENTRANCE CONTROL USING BAR CODE DISPLAYED LIQUID CRYSTAL DISPLAY

摘要

PURPOSE: A system and method for controlling the entrance and security using the liquid crystal bar-code are provided to reduce the cost waste through the lower cost for installing and maintaining the liquid crystal bar-code of a mobile terminal, and to facilitate the alternation of a new bar-code in case of losing the mobile terminal. CONSTITUTION: A member management server processes the registration according to the request of a member(S40). The member management server creates the bar-code containing the identification information of each member and grants the bar-code to the member(S41). The member management server transfers the bar-code to the designated mobile terminal of the member(S42). The bar-code is stored in the mobile terminal(S43) and a digital door lock scans the liquid crystal bar-code displayed to an LCD of the mobile terminal(S44), which transfers the scanned bar-code data to the member management server(S45). The member management server performs the authentication procedures by comparing the member identification number of the bar-code data with the member identification number of a DB(S46) and transfers the authentication result to the digital door lock(S47). The digital door lock performs the fixed processing according to the authentication result(S48), manages the bar-code use specification of every member, and transfers the relevant data to the member management server(S49).
