Every human has distinct physiological as well as behavioral characteristics and to recognize each individual we need a biometric system that provides a wide variety of reliable personal recognition schemes either in form of confirmation or determination. The purpose of such schemes is to make sure that the services are only accessed by a genuine user, and no one else use of it. This includes fingerprint, voice, face, gait, iris, signature, hand geometry etc. Mainly the biometric system consists of four main modules i.e. sensor module, feature extraction module, matching module and decision module. In a biometric system, sensor module is the first module so it is very essential to have accurate acquisition of data over there. In this paper various type of fingerprint sensors are discussed in detail. There are some parameters like pixel density, resolution, SN ratio, motion blur, gray scale etc. of these sensors which are also included. Sensors also encounter some challenges like durability, dry & wet finger, noisy data, spoof attacks etc. Finally the list of most deployed sensors with their parameters.
