How is ZOHO form different from the forms in Zoho CRM?

I have Zoho CRM+ and have been creating forms to embed in my websites but would like the capability of using a form at a trade show like icontact does, i.e., I can collect a new prospect on or offline and upload later plus I can use a QR or text to join feature. Will zoho forms accomplish this and will it integrate with ZOHO crm and Zoho campaigns automatically?
