Scanner Hardware Requirements

Simple Attachment

This method of image acquisition is intended for simple documents or images and therefore does not require anything other than the minimum TWAIN functionality listed below. In the event that a scanner is to be used for this attachment type that does not have a TWAIN driver or its driver fails to meet the minimum scanner requirements, a work around is to scan the image to the file system and then attach from that location within the capture program.

Batch Attachment

This method of image acquisition is intended for Document attachment (scanning Purchase Orders for example) and provides a more complex user interface. It also requires a scanner with a sheet feeder. In most cases, this limits the hardware to mid to high-end scanners.

TWAIN Requirements

Any scanner to be used with Documents Online must also come with a TWAIN driver and be a TWAIN compatible device. The following are the capabilities Documents Online will expect from the scanner and the TWAIN messages used during the scanning process. For the most part this should fall well within any minimum TWAIN implementation.

Custom Controller Pages

The "Custom Controller" BusinessPlus pages are designed to have special behavior, which provides a richer User Interface. However, they do not support column level security for any of their displayed fields. Below is a list of these screens:
