If In-Person Signing is enabled, you can have your signers sign a Template Link directly on one of your devices. In order to sign a document in person, simply look up your Template Link in your Templates list and click the righthand "Sign Now" button.
You will then be redirected to a page where your signer will be required to enter their name and email address. Once submitted, your signer will be redirected to the signing process and can complete it within a few steps. After signing your template, your client will receive a PDF copy of the signed document via email.
Please note that in order for In-Person Signing to work you need to make sure that your device is logged in to your Xodo Sign account.
