Apparatus and method for receiving fingerprint information through guide

Abstract

An electronic apparatus is provided. The electronic device includes a display, a fingerprint sensor disposed under the display, and a processor electrically connected with the display and the fingerprint sensor. The processor is configured to set a fingerprint sensing region at a location, which corresponds to a location where the fingerprint sensor is disposed, on the display if the electronic apparatus enters a state for registering a fingerprint of a finger, to display a first guide on the display such that the first guide at least partly overlaps the fingerprint sensing region, to obtain first fingerprint information through the fingerprint sensing region if the finger touches the first guide, to display a second guide on the display such that the second guide at least partly overlaps the fingerprint sensing region, and to obtain second fingerprint information through the fingerprint sensing region if the finger touches the second guide.
