Why is it useful to use an electronic signature on a mobile phone?

Knowing how to make an e-signature on a phone is important because they allow companies to legally approve contracts remotely.

Unlike handwritten signatures, which must take place in person, electronic signatures can be acquired through any electronic device, such as a computer, iPad, iPhone, or Android phone.

For business users operating remotely, these signatures are a cornerstone of daily business operations.

E-signature solutions can be used to hire employees, award service contracts, agree to proposals, and much more.

Is a signature on a phone legally binding?

Yes! Although electronic signature law varies from country to country, the major basis for electronic law legality in the US and EU comes from the Uniform Electronic Transactions Act (UETA) and the eIDAS Regulation, respectively.

Under these guidelines, documents with a valid digital signature from a phone or other device are considered legal and binding in the eyes of the law, as though the signer wrote their physical signature on a document.

In some ways, the term “electronic signature” is misleading because a digital signature doesn’t have to resemble a handwritten signature in any way.

Electronic signatures vs digital signatures

There are two basic types of signatures that you can create when trying to create a signed document on your phone: Electronic signatures and digital signatures.

Most legal definitions define an electronic signature as a “sound, symbol, or process” that is logically associated with a contract and the person who intends to sign it. 

This is why it’s possible to upload a virtual image of your signature and use it to sign a document.

However, this is risky for contracts and legal documents because of repudiation — the ability for signers to deny the authenticity of the signature.

That’s why we always recommend digital signatures for important documents.

Digital signatures use electronic identification methods, such as digital certificates, audit trails, personalized login information, or access codes attached to a signer’s identity to prove who signed the document.

A mobile app from a trusted e-signing solution like PandaDoc can ensure that when you create a signature on your phone, it  is valid, mobile-friendly, and has everything it needs to defend against repudiation.
