biometric security with the iPAQ Pocket PC h5400 series
. .
Care should be taken in establishing this control. If the maximum number of attempts is exceeded,
. .
then the user is prompted to indicate whether additional logon attempts are to be permitted, or if
. .
. .
the user desires to do a full reset of the iPAQ unit. If the user selects the full reset option when
. .
prompted by the application, all information stored in RAM and the iPAQ File Store will be lost
. .
. .
and the device will be returned to an as-shipped configuration.
. .
. .
. .
Important: When a full reset is performed, the following will result:
. .
. .
All data in RAM and the iPAQ File Store will be lost.
. .
. .
The fingerprint image that is used to establish a match will be lost and must be recreated.
. .
. .
Refer to the "enrolling your fingerprint" section in this document for instructions on
. .
establishing the fingerprint image.
. .
. .
A full reset can only be initiated when the user fails to authenticate themselves to the unit.
. .
. .
. .
Note: A full reset and a hard reset are not the same. A hard reset is performed by simultaneously
. .
pressing the two outer application buttons and the reset button on the bottom of the handheld. The
. .
. .
hard reset does not delete the iPAQ File Store.

The new SDK for the iPAQ Pocket PC h5400 is now available on the support portal for the iPAQ
. .
. .
Developer Program website. The SDK provides APIs found on the previous iPAQ Pocket PC
. .
platforms as well as a separate API and sample code for using the integrated wireless LAN radio.
. .
. .
Additionally, biometric API specifications, library files, and sample code has been posted to the
. .
site to enable developers to authenticate local users in their applications using the biometric reader
. .
. .
on the device.
