aes2660 driver supports devices based on the Authen``Tec AES2660 chipset.
aes2660 is part of libfprint and is developed by Vasily Khoruzhick.
This device can most commonly be found embedded in some laptops, standalone USB device exists - EikonMini
Vasily Khoruzhick wrote this driver based on bus traffic analysis and comparison with other Authen``Tec drivers. aes2660 shares almost all code with aes1660 driver, they only differ in init sequences and image width.
This is a swipe-type device which is similar to other Authen``Tec devices. Each frame is 192x8 pixels in size.
The fingerprint is always sent unencrypted over the USB bus. Device can encrypt image, but it's not supported. According to traffic logs, control traffic (commands) is never encrypted.
For Eikon``Mini scanner image quality is brilliant and imaging perfomance is good. MINDTCT finds over 40 minutiae on image.
Scanning technique is same as for other swipe sensors: don't scan too fast, don't scan too slow, don't put too much pressure on the sensor.
