In the specific use, when close proximity card reader or have the password via keyboard input, legitimate card signals the correct password, relay, power locks will open automatically, illegal card and the wrong password will be denied access, and tips on the display card is legitimate, the password is correct.System design is simple,the performance can be good,practical, strong.
