Digi-Seal™ enables users to sign any online form, or file upload. In order to use the Digi-Seal™, the user must first have their own digital signature certificate [Digi-ID™ [1]].
The simplest way to get each user their digital signature is to use the Total Trust Management™ [2] service. Or you can use the Digi-CA™ [3] system and issue the certificate yourself.
Either way, when placing your order [4], you should decide on the approximate number of people you want to use your online forms.
