Abstract
An electronic device may operate a fingerprint reader in a stationary finger mode in which the fingerprint reader captures a fingerprint from a user'"'"'s finger while the user'"'"'s finger is in a stationary position and may operate the fingerprint reader in a moving finger mode in which the fingerprint reader captures a fingerprint from the user'"'"'s finger while the user is swiping the finger across the fingerprint reader. The electronic device may use the moving finger mode when performing sensitive operations such as operations related to financial transactions. The electronic device may include near field communications circuitry. When activity is detected using the near field communications circuitry, the fingerprint reader may be operated in the moving finger mode. The fingerprint sensor may be activated when a proximity sensor detects the presence of a finger. Different actions may be taken by the device in response to detection of different fingerprints.

13. A method for using a fingerprint reader in an electronic device, comprising:
with control circuitry in the electronic device, operating the fingerprint reader in a stationary finger mode in which the control circuitry authenticates users by monitoring the fingerprint reader for a fingerprint associated with a user'"'"'s finger in a stationary position on the fingerprint reader and operating the fingerprint reader in a moving finger mode in which the control circuitry authenticates users by monitoring the fingerprint reader for a fingerprint captured by swiping the user'"'"'s finger across the fingerprint reader. - View Dependent Claims (14, 15, 16, 17, 18)

19. A method for operating a fingerprint reader in an electronic device having control circuitry, wherein the fingerprint reader includes a two-dimensional array of sensors arranged in rows and columns, the method comprising:
with the control circuitry, operating the fingerprint reader in a stationary finger mode in which each of the sensors is used in capturing a fingerprint from a finger that is in a stationary position on the fingerprint reader and operating the fingerprint reader in a moving finger mode in which only a subset of the rows of the two-dimensional array of sensors is used in capturing a fingerprint from a finger that is being swiped across the fingerprint reader. - View Dependent Claims (20)
