Utility cases are easy to spot, because
they usually do something other than offer
protection. The most common kind is the wallet case, which holds money, ID,
and credit cards. The Incipio Stashback and the Spigen
Valentinus are
great examples of cases that provide protection
as well as space for flat valuables.
Other utility cases include the Absolute
Technology LINKASE, which enhances weak
Wi-Fi signals, and the ReadyCase, which incorporates
several nifty tools into the case body,
including a bottle opener, screwdriver,
kickstand, and USB drive.
