What is the difference between an e-signature, a mobile signature, and a wet signature?

Under Turkish law, a secure electronic signature is legally equivalent to a wet signature; however, certain transactions (e.g., specific security and consumer transactions) are exceptions. We map which signature type each of your processes needs and flag the risky exceptions. The mobile signature is the one worth being clear about: it is a form of secure electronic signature, generated through the SIM card in a mobile phone, and not a separate category — it produces the same legal effect as a wet signature. A wet signature is the handwritten one on a physical document. In practice the mobile signature is the convenient route, because it carries the same validity without a separate e-signature device.
