For detailed information and guidelines on electronic signatures, please visit the official website of the European Union.

In the European Union, electronic signatures are legally accepted and have the same legal force as traditional handwritten signatures. This is stipulated in the eIDAS regulation (Regulation (EU) No. 910/2014), which ensures the standardization of electronic identification and trust services within the EU.

Electronic signatures offer several benefits such as faster processing, cost savings, increased efficiency, reduced paper usage and global reachability. This streamlines the signing process and reduces the need for physical paper.

Electronic signatures come with measures that guarantee both the authenticity of the document and the identity of the signer. Using various authentication methods, we can ensure that the signer is really the person he or she says he or she is while signing. This makes the signature legally strong and trustworthy. With Banqup's signing service, the security and authenticity of your documents and signatures is always at the forefront, as is the security of our system.

You received an email from afzender@unifiedpost.com because someone sent a document to you for you to sign through our service. The person who sent the document used your e-mail address with permission to contact you.

An electronic signature is the digital version of a handwritten signature. Like a traditional signature, an electronic signature confirms that the signer has seen and agrees to the contents of a document. The difference is that it is done digitally. In many jurisdictions, electronic signatures have the same legal value as handwritten signatures.
