St. Paul, MN, September 3, 2008: 3M [NYSE:MMM] helps define
portable security with the introduction of the 3M Mobile ID Reader -
the complete, hand-held data terminal for identity management on the
move. Designed for maximum portability, ease of use and reliability,
the 3M Mobile ID Reader is a durable, versatile, lightweight device
that reads MRZ and RF chip data from passports, ID cards and other
documents that serve as proof of identification.

3M Mobile ID Reader combines 3M's own reader technology with Psion
Teklogix's WORKABOUT PRO hand-held data terminal to scan passengers'
identity documents and capture their biometric data, verify these
against a watch list and compile a manifest for export to a border
control system. The unit's integrated touch screen and keyboard allow
the operator to correct or manually enter data. Additionally, a wide
range of wireless interface options, integral data storage and
biometric technologies allow the unit to be customized for specific
use.

Specialized Swiss Border Guard officers recently began using 3M
Mobile ID Reader for reading and processing passports and identity
documents of soccer fans traveling via train to the Euro 2008 event.
The lightweight, portable device from 3M provides Swiss Border Guards
with a way to accurately read identity documents on trains without
reliance on non-secure transmission of data over radio waves. Rather
than waiting minutes, officers can now authorize a document in a
matter of seconds.

"With this technology at our disposal, we were able to stop people
who thought trains offered a soft border entry point before they
reached Switzerland and the tournament, quickly disrupting their
travel plans," said Roger Zaugg, Commander Region North. "Officers
carry lots of equipment and are pleased that we have a device that is
small-enough to be transported in cars and is easily operated in the
confined space of a train carriage."

As a leading global provider of innovative security solutions that
use proprietary 3M technologies, including light management, optics,
films, adhesives and holography, 3M has helped to solve a wide range
of security problems for both government and private organizations,
protecting everything from passports and drivers' licenses to
electronic components and pharmaceuticals.

3M is a trademark of 3M.
