You can use the Require Signature on device check box in the Trigger Action window to ensure that during data entry an operator signs off on the data being entered before navigating to a different tag.
The signature is associated with the manually entered value and is stored as an image in the mobile database on the device. If an operator changes the value, the signature is discarded. If the new value violates a specified limit, the operator can be prompted to sign the new data.
Note: Frequent use of this feature can have significant impact on your mobile database size and performance.
The required signature action is currently only supported on Windows Mobile devices. On Windows XP/Vista Mobile PCs, this action is ignored.
