Most people sign on a phone by dragging a finger across the screen. The result looks a bit like their signature on a good day, and a lot like anyone else's on a bad one. If the signer later says "that wasn't me", a finger squiggle doesn't argue back very well.
A selfie does. A photo of the signer's face, taken at the moment they signed, is far harder to disown than a line on a screen. That's the whole case for it.
What a selfie signature is, in law
South Africa's Electronic Communications and Transactions Act recognises two tiers of electronic signature. The advanced tier comes only from an accredited provider who checks your identity up front. Everything else is an ordinary electronic signature, and that's what most business documents need: quotes, contracts, offer letters, policies, delivery notes.
A selfie signature sits in the ordinary tier, with better evidence attached. It isn't an advanced electronic signature, and no amount of camera work makes it one, because the difference between the tiers is accreditation, not technology. Our guide to advanced and ordinary electronic signatures covers the split in more detail.
What it shows, and what it doesn't
Be honest with yourself about this part, because it's where people oversell selfies.
A selfie shows who was holding the phone when the document was signed. Put that next to the time, the IP address and the device, and you have a good answer to "who signed this?".
It doesn't prove who that person is. Nobody compared the face to an ID book or a passport. If a stranger signs your contract with a confident smile, you have a clear photo of a stranger. For most small-business paperwork that's fine, because you already know the person you're dealing with, and the question in a dispute is whether they signed, not who they are. When you genuinely need identity verified by someone independent, you need the accredited tier.
When to use it
Use a selfie where a dispute about who signed would hurt. An employment contract, an equipment rental, a quote for a large job, a staff member's acknowledgement of a disciplinary policy. These are documents where "I never signed that" is a real risk, and a face on the record ends that argument early.
For a routine delivery note or a low-value order, a drawn signature is plenty. Asking for a selfie on everything makes people wonder what you're worried about.
When not to use it
A short list of documents can't be signed electronically at all in South Africa. Wills, the sale of immovable property and long leases of land are the ones a small business is most likely to meet. Those still need a handwritten signature on paper. A selfie doesn't change that, and neither does any other kind of e-signature.
The same goes for any document where a specific law asks for a signature and doesn't accept an ordinary electronic one. If you're not sure, our guide on whether electronic signatures are legal in South Africa walks through the exclusions.
Tell the signer what happens to the photo
A face is personal information, and the Protection of Personal Information Act expects you to collect it for a stated reason and keep to that reason. So ask before the camera starts, say why you want the photo, and don't use it for anything else. A selfie quietly reused as a staff profile picture is exactly the kind of thing that gets complaints.
Give the signer a way out, too. Some people won't take a selfie for perfectly good reasons, and a drawn signature is still a valid signature.
How it works in E·BIZI Papers
In E·BIZI Papers, Smile and Sign is a setting on each signing request. The signer opens the link in their email, agrees to the photo, fits their face in the oval and smiles. That one photo goes on the document in place of their signature and their initials. They can switch to drawing instead if they'd rather.
The sealed PDF carries a certificate of completion with the time, the IP address, the device and a fingerprint of the photo, so anyone can check later that the photo on file is the one taken at signing. It shows who signed. It doesn't prove who they are, and Papers doesn't pretend otherwise.
