Digital signatures are becoming the preferred technology for e-signing documents – whether that’s for internal, B2B or B2C signing workflows.
Digital signatures utilize accepted standards called Public Key Infrastructure (PKI) to ensure the highest security and acceptance. As a result, electronic signatures are widely accepted as legally binding and a secure way of signing documents. Around the world, organizations are embracing e-signatures as an underpinning technology to drive their digital transformation projects forward.
OneSpan offers a leading e-signature solution built on digital signature technology that can help you meet geographic requirements, such as those outlined in the EU’s eIDAS regulation.
