Consigne
Signing from a phone anywhere
On a site, in a lorry or at a client's home. What you need and what you do not.
Most delayed signatures are not delayed by doubts about the document: they are delayed because the person is not at a computer when it arrives, and by the time they are, they have forgotten.
What you need
| You need | You do not need |
|---|---|
| The link that was sent | To install any app |
| A connection, mobile data is fine | An account on the platform |
| To be able to read the document | A printer or scanner |
| And sometimes a verification code | A digital certificate, unless required |
Important
The right-hand column surprises signers most. Many people set the email aside thinking "this needs the office computer", and it does not: you open it, read it and sign with a finger.
What the journey looks like
- 1
Open the link
It goes straight to the document, with no sign-up or password.
- 2
Read it
Worth doing properly: it is what you are signing.
- 3
Verify who you are, if asked
A code arriving separately, to prove it is you.
- 4
And sign
With a finger or by accepting; a copy and evidence remain.
Watch out
If the document is long and complex, signing on a phone between two other things is not a good idea even though you can. The convenience of signing anywhere does not change what you are taking on by signing.
When there is no signal
In a basement site or a warehouse with no coverage, the link will not open. What works is preparing it beforehand or signing on the way out; what does not work is going back to paper "just for today", because that paper is the one nobody scans afterwards.
Worth knowing
Signing costs the signer nothing. Consumption is on the sender's side, and a signature made on a phone is worth exactly the same as one made on a computer.
›Is a finger signature valid?
Yes. The value comes from the evidence around it, not the stroke.
›Do I get a copy?
Yes, when it completes.
›What if I sign by mistake?
Tell the sender: they can void it and send again.
