Mini-clone
The mini-clone was a smaller version of the AT77C102: there were only 128 pixels compared to the 280 pixels of the regular version. This was much less expensive !
This version has never been released, because we found that the recognition results were too bad, confirmed on many different algorithms: width is not large enough for a good recognition. This was a confirmation of our study :
- J.F. Mainguet, Wei Gong, Anne Wang "Reducing Silicon Fingerprint Sensor Area" International Conference on Biometric Authentication ICBA 2004 Hong-Kong July, 15-17 2004 Lecture Notes in Computer Science, Volume 3072 / 2004, pp. 301 - 308
That said, competition released such kind of small sensors. Likely with bad results for FRR/FAR compared to "normal" width.
The AT77C102 for comparison.
