PDF forms allow the reader to type data into text fields – much like filling in a form on the web. Using Infix, you can fill in PDF forms you’re sent and distribute the results without any compatibility problems.
Why would you want to do this? For one thing, it’s quick; as the recipient, you can fill in the form and return it digitally without having to print it out (and either post or scan it). In fact, by using PDF forms, you might find you can pack away the fax machine for good and save a lot of paper in the process.
