To sign contracts with a qualified electronic signature (QES) – the legal equivalent of a handwritten signature – each co-signer must verify their identity. With DeepSign you and your business partners can remotely identify for free using our own DeepID mobile app. DeepID works with both passports and national IDs – and setup just takes minutes!

Discover our free digital ID

When you sign a document online you must be sure that your signature will be legally valid in that context. With the DeepSign online signature creator you have three types of electronic signatures recognised in Switzerland and the EU: qualified electronic signatures (QES), advanced electronic signatures (AES) and simple electronic signatures (SES).
