APPENDIX H SIGNATURE CAPTURE CODE
Introduction
CapCode, a signature capture code, is a special pattern that encloses a signature area on a document and
allows a scanner to capture a signature.
There are several accepted patterns that allow automatic ide
ntificatio
n of different signatures on the same
form. For example, on the federal tax return 1040 form there are three signature areas, one each for two joint
filers, and one for a professional preparer. By using different patterns, a program can correctly identify all three,
so they can be captured in any sequence and still be identified correctly.
Code Structure
Signature Capture Area
A CapCode is printed as two identical patterns on either side of a signature capture box, as shown in Figure
H-1
. Each pattern extends the full height of the signature capture box.
The box is optional, so you can omit it, replace it with
a single baseline, or print a baseline with an "X" on top of
it towards the left, as is customarily done in the US to indicate a request for signature. However, if an "X" or
other markings are added in the signature box area, these are captured with the signature.
