BioStation Fingerprint Terminal Overview

The BioStation incorporates a leading-edge fingerprint recognition algorithm - one of the most reliable fingerprint readers on the market.

The Biostation fingerprint reader offers an impressive biometric time & attendance solution suitable for offices, hotels and other organisations where a feature rich and attractive unit is required. Incorporating a colour LCD screen and high quality sound, the BioStation provides a modern user interaction with the option of using multimedia information. Various communication options including TCP/IP cabled and wireless LAN as well as USB memory stick, allow the BioStation to be used in many different locations.

The BioStation is a perfect solution for biometric time & attendance and access control.

Technology of Different Fingerprint Sensors

Optical Sensors
With optical sensors, the finger is placed on a plate and illuminated by LED light sources. Through a prism and a system of lenses, the image is projected on a CMOS image sensor. Using frame grabber techniques, the image is stored and ready for analysis.

Thermal Sensors
Thermal sensors contain an array of temperature measurement pixels which make a distinction between the temperature of the skin (the ridges) and the temperature of the air (in the valleys). One dimension of this sensor can be fairly small since a temperature scan is be obtained by sweeping the finger over the sensor.

Capacitive Sensors
Capacitive sensors use the difference between skin-sensor and air-sensor contact in terms of capacitive values. When a finger is placed on the sensor, an array of pixels measures the variation in capacity between the valleys and the ridges in the fingerprint.

Sensor Options

The BioStation is available with three different finger reader sensors. Each sensor type has its own advantages and disadvantages. Capacitive readers are more suitable for use with dirty or oily fingers - however they are more sensitive to damage. Optical readers are more robust however dirty / oily fingers do not read as well. Swipe (where the employee slides their finger down the sensor pad) is a compromise between the other two, but is only available with the basic BioStation.
