Simple Electronic Signatures (SES)

Definition and examples of Simple Electronic Signatures (SES) and how they are used in digital transactions.

Updated: Reading Time: ~7 Min

Simple Electronic Signatures (SES) are the most basic type of electronic signatures. They are widely used for situations where security is not a major concern and the risk of fraud is minimal. While not as secure as Advanced Electronic Signatures (AES) or Qualified Electronic Signatures (QES), SES still serve as a valid means of confirming agreement to the terms of a document. In this guide, we will explore what SES is, when to use them, and the legal framework that supports their use.

What is a Simple Electronic Signature (SES)?

A Simple Electronic Signature (SES) is defined as any electronic method that is used to indicate the signer's intent to agree to the terms of a document. The simplest forms of SES can be as basic as typing a name in an email or clicking an “I agree” button on a website. However, these methods do not provide strong security or authentication measures like more advanced types of e-signatures.

While SES lacks the verification and security measures of more advanced signatures, they are still legally recognized under most electronic signature laws and are widely used in everyday transactions.

Examples of SES

There are various examples of Simple Electronic Signatures (SES) used in daily transactions. Some common examples include:

  • Typing a Name: Signing a document by simply typing your name at the end of the document or in an email.
  • Clicking an "I Agree" Button: Many online services require users to click a button to agree to terms and conditions, which is considered an SES.
  • Scanned Signature: Scanning a handwritten signature and attaching it to a document electronically. This is one of the most common forms of SES used in non-official transactions.
  • Email Confirmation: Sending a signed email as an agreement to terms, such as confirming a meeting or order.

These examples demonstrate how SES are commonly used for everyday agreements. They are suitable for less formal transactions, but should not be relied upon for high-stakes or legal agreements without additional verification.

When to Use SES?

Simple Electronic Signatures (SES) are suitable for use in situations where the risks associated with fraud or misuse are low and where a higher level of security or identity verification is not necessary. Common use cases for SES include:

  • Non-Binding Agreements: SES can be used for non-legally binding agreements, such as confirming a meeting time or acknowledging the receipt of a document.
  • Informal Transactions: In cases where a quick, informal agreement is required (such as a purchase confirmation or an order for goods), SES are often sufficient.
  • Internal Documents: SES can be used within a company for low-risk documents like internal approvals or non-confidential forms.
  • Subscriptions and Sign-ups: When users agree to terms and conditions on websites or mobile apps, an SES can often be sufficient for the transaction.

While SES are legally valid for these purposes, they should not be used for formal, high-stakes contracts or documents requiring high security, such as business contracts or financial transactions, where a more secure e-signature method (like AES or QES) is preferred.

FAQ – Common Questions about Simple Electronic Signatures (SES)

Are Simple Electronic Signatures legally valid?

Yes, Simple Electronic Signatures (SES) are legally valid for low-risk agreements and informal contracts. They are recognized under Swiss law (ZertES) and the EU's eIDAS Regulation, but they may not be sufficient for high-stakes or formal contracts.

When should I use SES instead of other types of e-signatures?

SES is suitable for informal agreements, non-binding contracts, and low-risk transactions. If higher security or legal validity is required, such as in business contracts or financial transactions, you should consider using an Advanced Electronic Signature (AES) or Qualified Electronic Signature (QES).

Is a typed name considered a valid SES?

Yes, a typed name at the end of an email or document is a basic form of Simple Electronic Signature (SES). It is generally valid for informal agreements but may not be sufficient for more formal, high-stakes contracts.
