What Does S-signature Mean?

S Signature, also stylized as /s/ signature, is a generic term for any signatures that are created through means other than handwriting in pen and ink like wet signature.

These signatures mainly comprise electronic signatures which are used to sign soft copies of the documents online. These signatures gained popularity as business processes shifted more and more towards the internet and softcopies became more popular than hard copies.

These signatures are widely accepted by local as well as international laws. S-signatures do not have a strict form or dimension. In fact, S-signatures of two different individuals can vary greatly. In general, S-signatures are accepted as they fulfil the following rules:

  • An S-signature has to be present between two forward slashes (/signature/).
  • An S-signature can have English alphabet letters and/or Arabic numbers (0-9) only.
  • An individual signing the document can only include their own S-signature.
  • The S-signature should be followed by the printed name of the person who is signing the document.
