Sign‑me is a remote electronic signature solution that allows individuals and organizations to digitally sign documents using a web‑based or system‑integrated service. The cryptographic signature creation is performed in a secure environment operated by the trust service provider, while the signer authorizes each signature using strong authentication. The solution supports multiple signature levels under eIDAS and is suitable for both occasional and high‑volume signing scenarios. It enables legally binding signatures without requiring local signature cards or dedicated hardware.
