指纹传感器（又称指纹Sensor）是实现指纹自动采集的关键器件。指纹传感器按传感原理，即指纹成像原理和技术，分为光学指纹传感器、半导体电容传感器、半导体热敏传感器、半导体压感传感器、超声波传感器和射频RF传感器等。指纹传感器的制造技术是一项综合性强、技术复杂度高、制造工艺难的高新技术。
半导体指纹传感器因其制造工艺复杂，单位面积上传感单元多，包含高端的IC设计技术、大规模集成电路制造技术、IC芯片封装技术等，所以半导体指纹传感器几乎全部是由IC技术发达的国家或地区，如美国、欧洲、台湾等地设计、制造的。一颗不足0.5平方厘米的晶片表面集成了10000个以上的半导体传感单元。内部还包括了自动增益电路和逻辑控制芯片，以及串行、并行、USB等接口电路。目前半导体指纹传感器的灵敏度高，分辨率也达到了500dpi或以上。其功能已经突破了单一的传感能力，加上软件配合，可以用做全向导航器。半导体指纹传感器目前朝小型化方向发展。2004年以前以1平方厘米见方的方型为主，目前多为滑动式SWIPE芯片。全球最小的滑动式采集芯片只有12x5 mm,是由Authentec最近推出的1610。
