 | Live Finger Detection | New patented sensor detects fake fingerprints made of paper, film, silicone and rubber |
 | Fingerprint | Convenience – it does not require users to carry special tools for verification. It is a high-tech fingerprint recognition system that uses fingerprints that have no risk of replication or unauthorized use. |
 | RF Card (option) | Can be embedded in the fingerprint recognition terminal for double or triple security or to use with unclear fingerprints. |
 | TCP/IP | TCP/IP network method that allows for expansion between terminals/servers or terminals/terminals. Easy to install and operate. |
 | Intelligent capture | The fingerprint recognition algorithm authenticates dry or wet fingerprints fast and accurately for various users. |
 | High Performance CPU | VIRDI Series is equipped with high-capacity 32bit CPU for faster and more accurate verification. |
 | Memory | Minimum of 4MByte (approx. 3,600 users) and maximum of 8MByte (approx. 8,300 users) |
 | Auto sensing | Automatically recognizes fingerprints when finger is presented. |
 | Multiplayer | Can be applied to government offices, companies, and financial institutions to build access control, Time and Attendance management systems. |
 | Motion sensor | Terminal recognizes user approach and automatically turns on LCD and keypad lights. Able to read device at night and saves unnecessary energy waste. |
 | Authentication | Supports complex authentication using fingerprints, RF Card, and/or ID/Password for greater safety. |
 | Operation mode | The device can be set up for Access Control, Time and Attendance management, and Cafe management without additional equipment. |
