A Wet Signature is a handwritten signature made using ink or another physical medium on a paper document, serving as a legally binding form of authentication. It is widely used in employment contracts, vendor agreements, compliance documents, and financial transactions to ensure authenticity, accountability, and legal validity. Despite the rise of digital signatures, wet signatures remain crucial for regulatory compliance, official approvals, and documents requiring notarization.

Industries such as manufacturing, retail, logistics, e-commerce, and facility management services (FMS) frequently require wet signatures for employment agreements, payroll authorization, and vendor contracts. Businesses managing contract workers, apprentices, and project-based employees must maintain secure documentation processes, proper record-keeping, and compliance with labor laws when handling wet-signed documents. By integrating hybrid signature solutions, secure document storage, and streamlined verification protocols, companies can enhance operational efficiency, reduce paperwork delays, and ensure regulatory compliance.
