The GV-GF Fingerprint Reader works with GV-AS / GV-EV Controller and GV-ASManager to create a complete access control system.
With the GV-GF Fingerprint Reader only, you can also enroll and manage users through the supplied Manager Enroll Card and Delete Card, along with optional MIFARE user cards.
Work with GV-AS / GV-EV Controller and GV-ASManager
Three types of access modes: card only, fingerprint only and card plus fingerprint
Fingerprint templates stored on the user card
Three types of communication interfaces for connecting with GV-AS Controller: Wiegand 26, RS-485 and TCP/IP (LAN)

1. The support for RS-485 connection has ended with GV-GF1911 / 1912 from GV-AS21 /41 / 81 series Controller firmware V1.41 and GV-ASManager V4.4.3.
2. For GV-GF1911, an optionally purchased PC Service Package, which includes a USB cable, is required to work with the Fingerprint Only Mode.
3. For Card + Fingerprint Mode and Card Only Mode, it is required to purchase GeoVision to work with.
4. Data synchronization with GV-AS Controller and GV-ASManager through LAN is only supported
when the following controller firmware version and software version work together:
GV-AS100 / 110 / 120: V1.06 or later
GV-AS400: V1.04 or later
GV-AS210 / 810: V1.0 or later
* GV-AS410: V1.1 or later
* GV-AS2110 / 4110 / 8110: V1.23 or later
The GV-Hub V2 adds four RS-232/RS-485 serial ports through the computer's USB port, allowing connection between the fingerprint reader and the computer.
The GV-COM V2 can convert the standard RS-232 signal, through USB connector, to RS-485 signal, allowing connection between the fingerprint reader and the computer.
The GV-COM V3 can convert the standard RS-232 signal, through USB connector, to RS-485 signal, allowing connection between the fingerprint reader and the computer.
The GV-NET/IO Card is a RS-485 / RS-232 interface converter that provides 4 inputs and 4 relay outputs. Using the GV-NET/IO Card, you can connect the fingerprint reader to the computer.
PC Service Package
The package includes a USB cable for connecting the fingerprint reader to a computer and a reader mount to hold the reader for fingerprint enrollment.
