Companies from various industries rely on fidentity’s identification and signing solutions.

Sign digitally in 2 minutes. With the Gold Standard.

A signature on paper makes digital processes cumbersome. Digital signatures with a few clicks have no legal effect. In Europe and Switzerland, the law stipulates that so-called “qualified electronic signatures” (QES) have the same legal effect as handwritten signatures. fidentity SIGN is audited by KPMG and complies with the legal requirements (CertEs in Switzerland, eIDAS in the EU). So you can have both. A completely digital process and legal security. With SIGN, you and your customers can sign easily, quickly and securely – at any time and from any location.

fidentity SIGN

For all contracts.

Digital signatures from fidentity are suitable for all types of contracts, especially when written form is required by law or there is a high liability risk. SIGN from fidentity fulfills the requirements of a Qualified Electronic Signature according to ZertES and eIDAS and is legally equivalent to a handwritten signature.

Legally compliant in EU and Switzerland

A solution for the whole of Europe

The Qualified Electronic Signature is legally equivalent to the handwritten signature in Switzerland(ZertES) and the EU(eIDAS). It has the highest probative value, but requires the signer to identify himself with official identification. Thanks to the seamlessly integrated identification with IDENT, the digital signature is completed in just a few minutes.

Comply with formal requirements

Many contracts are subject to explicit or implicit formal requirements. A credit agreement with consumers must be signed by hand or signed with a QES, otherwise it will not come into effect. An employment contract is valid, but fixed-term clauses are not enforceable unless signed with QES. Avoid risks due to formal errors and sign important documents with QES.

Comply with regulation

In many countries, e.g. Austria, Switzerland, Luxembourg or Romania, a QES proves that the identification is sufficiently strong to comply with the due diligence requirements of money laundering regulation. Financial service providers can therefore fulfill all regulatory requirements by combining IDENT and SIGN.
