What is a simple electronic signature (SES)?
In Switzerland and Europe, electronic signatures are classified according to the ZertES and eIDAS standards as simple electronic signatures (SES), advanced electronic signatures (AES), and qualified electronic signatures (QES). The simple electronic signature (SES) is the most basic form of digital signature. It does not require any special identity verification or cryptographic security mechanisms. An SES can be, for example, a typed signature, a scan of a handwritten signature, or clicking an “I agree” button.
When is the SES used?
The SES is suitable for documents that do not have high legal requirements. Examples include:
- Internal documents: Employee evaluations, reports, or general communications.
- Order and contract forms: For simple business transactions without complex contractual terms.
- Declarations of consent: Consent to privacy policies or terms and conditions.
- Simple non-disclosure agreements (NDAs): When no detailed legal protection is necessary.
How does the SES work digitally?
Simple electronic signatures are often implemented via digital platforms or software solutions. Various methods can be used:
- Signature entry: Users type or draw their signature directly into a digital document.
- Email confirmation: A signature is verified by confirming an email address or clicking on a link.
- Authentication via user accounts: Users confirm their identity by logging into a familiar system.
- Checkboxes and click mechanisms: Consent is given by checking a box or clicking a button.
Advantages of digital SES
- Speed: Documents can be signed in seconds without the need for a physical printout.
- Ease of use: No special software or hardware required.
- Flexibility: Sign from anywhere with an internet-enabled device.
- Cost savings: Reduction in printing, shipping, and archiving costs.

Frequently asked questions
A simple electronic signature can be represented in various ways. Examples include a scanned handwritten signature inserted into a digital document, the name at the bottom of an email, or clicking an “Accept” button during an online transaction. This form of signature serves as consent or confirmation, but does not have high security requirements.
According to the eIDAS Regulation, a simple electronic signature is “data in electronic form which is attached to or logically associated with another electronic file and which is used for signing.” This means that any digital mark that links the identity of the signatory to a document can be considered a simple electronic signature. However, it does not provide guaranteed authenticity or integrity.
A simple electronic signature is sufficient if there are no special legal requirements for the signature. Typical use cases are internal documents, orders, or simple contracts with low legal risk. It is particularly suitable for processes that require quick and uncomplicated approval but do not require strict identity verification.
Yes, a simple electronic signature is generally legally valid. However, it is not sufficient for all documents. In cases with higher legal requirements, such as official documents or certain contracts, an advanced or qualified electronic signature may be required. Companies should therefore check which type of signature is suitable for their specific application.

Qualified electronic signature (QES) – simply explained
In an increasingly digital world, legally valid electronic signatures are essential. The qualified electronic signature (QES) is the most secure and legally binding form of digital signature. Learn how QES works, when it is required, and how you can sign your documents securely and without media discontinuity using signeer from mesoneer.

Advanced electronic signature (AES) – simply explained
Legally valid and secure electronic signatures are essential in the digital business world. The advanced electronic signature (AES) offers significantly higher security than the simple electronic signature (SES), as it requires a verified identity of the signatory and uses technical protection mechanisms against manipulation. As a result, it offers greater legal certainty and probative value, for example for business contracts or sensitive documents. However, the FES is not sufficient if written form is required by law. In such cases, a qualified electronic signature (QES) is mandatory, as only it replaces the legally required written form.

ZertES and eIDAS: Digital Signatures in Switzerland and the EU
Paperwork is a thing of the past – but how do digital signatures remain legally secure? Digital signatures are becoming increasingly important as companies seek to make their processes more efficient and sustainable. But how secure are digital signatures? The legal framework is crucial for their legal validity. In Switzerland and the European Union (EU), the ZertES and eIDAS regulations set the standards for electronic signatures.
