Adobe Acrobat Professional can do much than just create static PDFs. The Professional version creates interactive forms that collect data.
To start creating your form, open up Acrobat and select the Forms->Start Forms Wizard then choose between one of the options:
An existing electronic document – Converts a Word, Excel or other file types to PDF, then automatically detects & creates interactive form fields based on the existing artwork. You can then modify or add extra fields.
A paper form – Acrobat will use your connected scanner to scan a paper document, recognise the text with OCR, then recognize and creates interactive form fields based on the existing artwork.
No existing form – Windows users can open the bundled LiveCycle Designer application. LiveCycle Designer allows you to either design a form from scratch by dragging and dropping form objects or using one of the many bundled templates
