Form with Digital Signature

[bkurzbuch]

Not sure if this is the correct place for this question. I have a variable form that will be going on a Marcom web site. At the bottom of this form, which is a payroll deduction form. There is a spot for a digital signature.
I've never had to account for a digital signature before. Does Marcom have any functionality for this? How would I handle something like this.
