The server causes the application to display on the display screen of the mobile device an option to electronically authenticate using a biometric credential. The server receives a selection indicating acceptance of use of authenticating using the biometric credential.

Abstract: Viscometers and viscometry methods are disclosed. In one general aspect, a fluid is driven through capillary tubes with different inside volumes, and successive images of the fluid are acquired as it advances through the inside volume of the capillary tubes. A range of different viscosity values of the fluid are derived from the successive acquired images, and results of this step are reported in a manner that provides insight into non-Newtonian effects in the fluid. In another general aspect, a viscosity value is selected based on detected pressure levels.
