... FCD4B14 has a linear shape, allowing for the capture of a fingerprint image by sweep- ing the finger across the sensing area. After capturing several images, Atmel proprietary software can reconstruct a full 8-bit fingerprint image, if needed. FCD4B14 has a small surface combined with CMOS technology, and a Chip-On-Board or ceramic dual-in-line package assembly ...
