109 Financial Institutions Now Live With Mobile Deposit, 333
                              Signed

SAN DIEGO, May 21, 2012 (GLOBE NEWSWIRE) -- Mitek Systems, Inc.,
(Nasdaq:MITK) (www.miteksystems.com), a leading mobile imaging software
solutions provider, today announced that approximately $10 billion in
mobile deposits have been enabled by Mitek's mobile imaging technology.
Mobile Deposit(R) is Mitek's mobile remote deposit capture (RDC)
solution that enables consumers and businesses to make deposits by
snapping photos of checks using camera-enabled smartphones and tablets.
The growing adoption of Mitek's technology is also evident in the
transaction volume, which increased more than 143 percent during the
six-month period ending December 2011.

"Hitting the $10 billion deposit milestone is an exciting proof point
in the value and growth of Mobile Deposit, particularly given that just
a few short years ago some were questioning if this technology would
take off," said Mitek Systems' President and CEO, James DeBello. "We
now have agreements signed with 333 financial institutions through our
partners, including eight of the top eight U.S. banks ranked by asset
size, who are using Mobile Deposit as a cornerstone of their mobile
strategy."

In a recent press release, ING DIRECT reported that for direct banking,
remote deposit capture "is the next innovative trend." Additionally, in
a commissioned survey designed to uncover consumers' checking
preferences, ING DIRECT found that, "about a third (32 percent) of
Americans who have never used remote deposit capture said they would
use the technology in the future when it became available."

Mitek Systems President and CEO Jim DeBello will present, "Mobile
Imaging: The Strategic Imperative", at the NetFinance conference Mobile
Channel Focus Day on Monday, May 21, 2012 from 2:20 -- 2:40 p.m.
NetFinance, a conference for e-commerce and marketing executives in
financial services, is being held at the Sheraton Wildhorse Pass,
Chandler, Ariz., May 21 --23, 2012. Mitek Systems will also be
demonstrating Mobile Deposit and Mobile Photo Bill Pay in booth number
24 during exhibit hours.

Mitek's Mobile Deposit technology is used by hundreds of financial
institutions to enable seamless, secure and fast mobile deposits for
their customers. Mitek's patented imaging technology solves the
difficult challenges presented with remote deposit capture including
the automatic correction of photographic and physical problems, such as
photos of checks that may be wrinkled, skewed, distorted, or taken
under poor lighting conditions. Mitek's technology creates industry
compliant images for downstream bank processing.
